Evaluation and treatment of men with biochemical prostate-specific antigen recurrence following definitive therapy for clinically localized prostate cancer

Early detection and monitoring by serum prostate-specific antigen (PSA) measurement has increased the number of men presenting with potentially curable prostate cancer. Most will choose radical prostatectomy or some form of radiation therapy for treatment, but some will have evidence of biochemical disease recurrence following therapy, shown by a rising PSA level without other clinical evidence of disease. Radical prostatectomy involves the removal of all prostate tissue, causing the serum PSA to decline to undetectable levels within four to six weeks following surgery; a subsequent rise in the serum PSA to a detectable level indicates disease recurrence. Patients should be evaluated to assess whether rising PSA levels indicate local recurrence or early metastatic disease. The advantages of salvage radiation, endocrine therapy, and other treatment modalities in local disease recurrence must be weighed against potential side effects and the resulting decrease in quality of life. Radiation therapy does not immediately eradicate all PSA-producing cells; therefore the persistence of a detectable PSA does not necessarily imply residual cancer, but rising PSA levels indicate treatment failure. Salvage surgery can be performed after radiotherapy for the purpose of removing all viable cancer cells, but should be weighed against a higher incidence of surgical complications; cryoablation offers a less invasive therapeutic modality.     

Guía clínica para el manejo del nódulo tiroideo y cáncer de tiroides durante el embarazo

Special considerations are warranted in management of thyroid nodule and thyroid cancer during pregnancy. The diagnostic and therapeutic approach of thyroid nodules follows the standard practice in non-pregnant women. On the other hand, differentiated thyroid cancer management during pregnancy poses a number of challenges for the mother and fetus. The available data show that pregnancy is not a risk factor for thyroid cancer development or recurrence, although flare-ups cannot be completely ruled out in women with active disease. If surgery is needed, it should be performed during the second term or, preferably, after delivery. A majority of pregnant patients with low-risk disease only need adjustment in levothyroxine therapy. However, women with increased serum thyroglobulin levels before pregnancy or structural disease require regular thyroglobulin measurements and neck ultrasound throughout pregnancy. Pregnancy is an absolute contraindication for radioactive iodine administration.     

Correlation between Serum Level of Monocyte Chemoattractant Protein-1 and Postoperative Recurrence of Spinal Tuberculosis in the Chinese Han Population

ObjectiveTo correlate serum level of monocyte chemoattractant protein-1 (MCP-1) with postoperative recurrence of spinal tuberculosis in the Chinese Han population.MethodsPatients of Han nationality with newly diagnosed spinal tuberculosis were consecutively included in this study. At different time points postoperatively, serum level of MCP-1 was determined using an enzyme linked immunosorbent assay. Recurrence of spinal tuberculosis after surgery and during the follow-up period was recorded. The correlation between serum MCP-1 level and recurrence of spinal tuberculosis was analyzed.ResultsA total of 169 patients with spinal tuberculosis were included in the study and followed up for an average of2.2±1.3 years (range, 1–5 years). Of these patients, 11 had postoperative recurrence of spinal tuberculosis. The patients’ serum level of MCP-1 increased significantly after postoperative recurrence of spinal tuberculosis. Once the symptoms of recurrence were cured, the serum level of MCP-1 decreased significantly and it did not differ from patients without disease recurrence.ConclusionPostoperative recurrence of spinal tuberculosis is likely to increase the serum level of MCP-1.

摘要 目的：探讨血清人附睾蛋白4（HE4）、血管内皮生长因子（VEGF）、单核细胞趋化因子-1（MCP-1）及CC趋化因子配体20（CCL20）与乳腺癌患者保乳术后局部复发的关系。方法：选择2015年7月~2018年7月期间本院收治的乳腺癌患者312例作为研究对象,均符合保乳术手术指征,成功实施乳腺癌保乳术,所有患者均随访3年。检测两组血清HE4、VEGF、MCP-1、CCL20水平情况,单因素及多因素Logistic回归分析影响术后局部复发的因素。使用受试者工作特征（ROC）曲线分析HE4、VEGF、MCP-1、CCL20水平单独及联合检测对保乳术后局部复发的预测价值。结果：随访过程中失访6例,剩余的306例患者根据随访结果,分为局部复发组27例、无局部复发组279例,局部复发率为8.82%。局部复发组的血清HE4、VEGF、MCP-1、CCL20水平均高于无局部复发组（P<0.05）。单因素分析结果显示,乳腺癌患者保乳术后局部复发与年龄、淋巴结转移、切缘状态、人表皮生长因子受体2（Her-2）、细胞增殖相关抗原（Ki-67）、术后规范化疗、术后足程放疗有关（P<0.05）。多因素Logistic回归分析结果显示术后规范化疗、年龄偏高、术后足程放疗是保乳术后局部复发的保护因素,HE4、VEGF、MCP-1、CCL20水平偏高,切缘状态、Her-2、Ki-67阳性以及淋巴结转移是保乳术后局部复发的危险因素（P<0.05）。HE4、VEGF、MCP-1、CCL20联合应用预测乳腺癌患者保乳术后局部复发的效能高于单一指标应用。结论：乳腺癌保乳术后局部复发患者体内HE4、VEGF、MCP-1、CCL20水平高表达,四指标联合检测可辅助预测保乳术后局部复发。且乳腺癌患者保乳术后复发还受到切缘状态、Her-2、Ki-67等多种因素的影响。     

Serum changes in trace elements during thyroid cancers

The objective was to examine changes in trace elements due to thyroid cancer in humans. Serum levels and tissue contents of trace elements (Zn, Cu, Mn, Mg, Fe and Se) were measured in 43 patients with thyroid cancer before and 4 days after surgery were compared to normal values. The serum levels of zinc in cancer patients were lower than those of normal subjects. Surgical removal of the cancer resulted in the restoration of these levels. Although serum Cu levels in patients were not different from normal, but post-operatively these levels rose significantly (p < 0.001). Levels of Fe, Mg and Mn were significantly lower (p < 0.001) post-operatively. There was no significant change in Serum Se levels. The thyroid tissue contents of these trace elements did not show a difference between the normal (Juxta-tumor) thyroid tissue and the cancerous lesion. Out of the six trace elements examined, the decrease of serum levels of zinc in cancer patients may be linked to the disease condition. It is suggested that this change: (a) may be used to demonstrate successful cancer surgery and (b) may have implications for a long-term follow-up of thyroid cancer patients.

Postoperative Serum Levels of sCD26 for Surveillance in Colorectal Cancer Patients

One of the main aims of the follow-up after curative resection of colorectal cancer is the early detection and treatment of tumor recurrence. We previously demonstrated decreased preoperative soluble CD26 (sCD26) levels in serum from colorectal cancer patients. We extended now the study to investigate if sCD26 levels in postoperative serum serve as marker of recurrence of the disease during surveillance. Soluble sCD26 was measured in pre- and postoperative serum samples of 43 patients with primary colorectal cancer. Carcinoembryonic antigen, carbohydrate antigen 19.9 and 72.4 levels were also measured during surveillance. The average follow-up period was 41.8±20.8 months. sCD26 levels during follow-up showed well-defined patterns in patients without disease (n = 28), and in patients with tumor persistence (n = 2), local recurrence (n = 3) or distant metastasis (n = 10). Disease-free patients showed stable levels between 460–850 ng/mL during follow-up, while high (over 850 ng/mL) and unstable sCD26 levels were found before recurrence was diagnosed. The mean maximum/minimum sCD26 ratios during surveillance were 1.52, 2.12 and 2.63 for patients with no recurrence, local recurrence and metastasis, respectively (p = 0.005). From the cut-off obtained from a receiver operator characteristics (ROC) curve built with the maximum/minimum sCD26 ratios and the upper and lower cut-offs of sCD26, we were able to discriminate patients with and without recurrent disease. We propose that the measurement of serum sCD26 during the follow-up of patients diagnosed of colorectal cancer could be valuable for the early detection of local and distant recurrence. A large, randomized, prospective trial should be performed to confirm our findings.     

青岛地区某医院12年甲状腺癌发病模式变迁

目的:探讨青岛地区某医院12年甲状腺癌的发病趋势和病理类型分布。方法:回顾性分析2001-2012年于青岛大学附属医院行手术切除的甲状腺癌患者的发病年龄、性别比例、手术数量以及病理类型构成比的变化。结果:12年来手术治疗甲状腺癌2421例,其中乳头状癌(PTC)占94.13%,滤泡状癌(FTC)占3.02%,髓样癌(MTC)占2.15%,未分化癌(ATC)占0.70%。甲状腺癌手术数量呈逐年递增趋势,尤以近4年升高显著,其病理类型以PTC为主,构成比例由79.63%上升至97.47%。四类甲状腺癌均以女性多见(男女比例1:1.38-1:4.37)。甲状腺癌的平均确诊年龄为46.80岁,PTC最低(46.48岁),ATC最高(64.25岁)。结论:青岛地区甲状腺癌发病数量呈逐年递增趋势,PTC是最常见的病理类型,其构成比例上升明显,其他类型相对下降。PTC的发病可能与高碘有关。     

Antioxidants in patients receiving total parenteral nutrition after gastrointestinal cancer surgery

Total parenteral nutrition (TPN) is essential for patients with postoperative impairing gastrointestinal function who are unable to receive and absorb oral/enteral feeding for at least 7 days. Oxidative stress plays a major role in the ethiopathogenesis of cancers. In this study, total antioxidant status (TAS), glutathione peroxidase (GPx), superoxide dismutase, malondialdehyde and ascorbic acid were studied in patients operated because of small intestine, colorectal or pancreatic cancer and subsequently receiving TPN in comparison with patients receiving standard nutrition after the operation. TAS level and GPx activity were decreased in patients with small intestine cancer but did not differ in patients with colorectal and pancreatic cancer before and after surgery. In all patient groups receiving TPN, superoxide dismutase activity after the surgery was kept at the same level as before. On the fifth day after the surgery, malondialdehyde concentration in each group was restored to the value observed before surgery. On the fifth day of TPN treatment, ascorbic acid concentration was increased in every group of patients. TPN applied during the postoperative period alleviates oxidative stress resulting from surgery. In the case of small intestine cancer, the addition of vitamins and antioxidants to the nutrition mixture seems to result in depletion of antioxidant enzymes' activities.     

Clinical significance of serum gastrin levels in patients with colorectal cancer

AIMS: An association between elevated serum gastrin levels and the presence of human colorectal cancer has been reported, and gastrin has been shown to stimulate the growth of experimentally induced colon neoplasia. The aim of this study was to determine the preoperative and postoperative concentrations of serum gastrin in 53 patients with colorectal cancer and to assess the correlation between gastrin levels and tumor characteristics and prognosis. MATERIALS AND METHODS: A prospective study was performed over a six-year period during which 53 patients received potentially curative surgery for colorectal cancer. The prognostic variables used for the analysis included age, sex, tumor site, stage and degree of differentiation, preoperative and postoperative serum values of carcinoembryonic antigen (CEA) and gastrin, cancer-related mortality, and survival. CEA and gastrin serum values were determined using radioimmunological methods. Follow-up was carried out with clinical and radiological tests. RESULTS: The mean preoperative gastrin concentration was 51.2+/-27.4 pg/mL (range 12-146). Significantly increased serum gastrin concentrations, which returned to normal after surgery, were detected only in patients with well-differentiated cancer (74.2+/-28.3 pg/mL; moderately differentiated, 52.1+/-23.8; poorly differentiated, 29.9+/-12.3, p=0.02). The prognosis was unrelated to serum gastrin level; instead, tumor stage, preoperative CEA value, and degree of differentiation affected patient survival. CONCLUSIONS: This study showed that the serum gastrin concentration is not an appropriate clinical oncogenic factor. Although occurring only in well-differentiated tumors, serum gastrin is unrelated to the prognosis of patients with colorectal cancer.     

Management of Hypothyroidism and Hypothyroxinemia During Pregnancy

ObjectiveTo review the diagnosis and management of hypothyroidism during pregnancy, in the preconception period, and in the postpartum period.MethodsA literature review of English-language papers published between 1982 and 2022, focusing on the most recent literature.ResultsDuring pregnancy, thyroid function laboratory tests need to be interpreted with regard to gestational age. Overt hypothyroidism, regardless of the thyroid-stimulating hormone (TSH) level, should always be promptly treated when it is diagnosed before conception or during pregnancy or lactation. Most women with pre-existing treated hypothyroidism require an increase in levothyroxine (LT4) dosing to maintain euthyroidism during gestation. LT4-treated pregnant patients need close monitoring of their serum TSH levels to avoid overtreatment or undertreatment. There is no consensus about whether to initiate LT4 in women with mild forms of gestational thyroid hypofunction. However, in light of current evidence, it is reasonable to treat women with subclinical hypothyroidism with LT4, particularly if the TSH level is >10 mIU/L or thyroperoxidase antibodies are present. Women who are not treated need to be followed up to ensure that treatment is initiated promptly if thyroid failure progresses. Additional studies are needed to better understand the effects of the initiation of LT4 in early gestation in women with subclinical hypothyroidism and hypothyroxinemia and determine optimal strategies for thyroid function screening in the preconception period and during pregnancy.ConclusionThe diagnosis and management of hypothyroidism in the peripregnancy period present specific challenges. While making management decisions, it is essential to weigh the risks and benefits of treatments for not just the mother but also the fetus.     

Recurrence following transsphenoidal surgery for acromegaly.

The long-term results of transsphenoidal adenomectomy and the incidence of possible recurrences were studied in 61 patients who had normal basal serum growth hormone (GH) levels 1 week after surgery. The patients were followed up for an average of 6.0 years (range: 1.5-14.0 years) by repeated measurements of GH, oral glucose tolerance testing (OGTT) and at the last follow-up visit also by assaying somatomedin C levels. In 4 of the patients, the basal GH levels had increased to values above 5 ng/ml. In 43 patients, a normal suppression of GH during an oral glucose load was observed shortly after surgery. In only 2 of these cases did a transiently inadequate suppression develop during the follow-up period, although clinical acromegaly did not recur and the somatomedin C levels remained normal. It is concluded that recurrence of active acromegaly is unlikely to occur in patients who achieve a normal glucose-induced suppression of GH levels shortly after adenomectomy. As such, an OGTT provides better prognostic information than basal human GH level measurements and may give a clearer and earlier indication of surgical success.     

甲状腺再次手术治疗的临床分析

目的:探讨甲状腺再次手术的原因、手术方式的选择和手术效果以及患者的预后情况。方法:统计哈尔滨医科大学附属第二医院普外科2001年1月到2015年9月期间收治的1600例初次行甲状腺手术的患者,回顾分析其中175例再次行甲状腺手术患者的临床资料。结果:甲状腺再次手术采用双侧甲状腺次全切除术为92例,单侧甲状腺次全切除术为72例,甲状腺癌根治术为11例。甲状腺再次手术患者术后出现甲状腺功能减退、气管和喉返神经损伤、出血以及缺钙引起的手足抽搦等概率高,与首次手术比较差异有统计学意义(P0.05)。术后1年内对再次手术的患者进行随访,其中复发12例(病理确诊为甲状腺癌3例,结节性甲状腺肿9例),其他类型甲状腺疾病无复发。结论:甲状腺再次手术较初次手术难度较大,术中及术后并发症较多,再次手术应谨慎选择术式及术中精细操作。     

Multielement analysis in serum of thyroid cancer patients before and after a surgical operation

Concentrations of trace elements Zn, Cu, Fe, Mn, Mg, and Sr in the serum of 50 thyroid cancer patients and 50 healthy controls were analyzed comprehensively by Pattern Recognition Analysis Method. Based on the Principal Component Analysis Method, Zn, Cu, and Sr were found to be the principal elements with significant variations between patients and healthy controls. According to the Mahalanolis Distance Decision and Nonlinear Mapping Methods, the trace elements levels in the serum of cancerous patients were found significantly different from that of controls. For 16 thyroid malignant tumor patients who underwent surgery, sample points of patients after surgery were directional away from corresponding points before surgery. However, an overlapping was found and separation between two groups of points was not complete. This finding suggests that there may be a latency period for the restoration of trace element levels after removal of the malignant tumorous tissue.     

Life events and breast cancer prognosis.

OBJECTIVE--To determine whether psychosocial stress, in the form of adverse life events and social difficulties, depressive illness, or lack of confiding relationships, shortens the postoperative disease free interval in breast cancer patients. DESIGN--Prospective follow up of a cohort of newly diagnosed breast cancer patients for 42 months after primary surgical treatment, using a life events and social difficulties schedule (LEDS) and assessment of depressive symptomatology (DSM-III). SETTING--Patients recruited from breast clinics in Southampton and Portsmouth were interviewed in their homes. PATIENTS--204 women (83% of 246 consecutive cases) treated either by mastectomy or wide excision followed by radiotherapy interviewed four, 24, and 42 months after operation. MAIN OUTCOME MEASURES--Hazard ratios for relapse of breast cancer in relation to various measures of psychosocial stress. Relapse was defined as local recurrence or distant metastasis, or both, with histological or radiological confirmation and timed from the month when clinical symptoms began. RESULTS--After adjustment for age and axillary lymph node involvement, the hazard ratio associated with severe life events or social difficulties (excluding "own health" ones), or both, during the year before breast cancer surgery was 0.43 (95% confidence interval 0.20 to 0.93); for those during the follow up period it was 0.88 (0.48 to 1.64). For prolonged major depression before surgery and during the follow up period, hazard ratios were 1.26 (0.49 to 3.26) and 0.85 (0.41 to 1.79) respectively. For absence of a full confidant the figures were 0.93 (0.42 to 2.09) and 0.86 (0.38 to 1.93). CONCLUSION--These results give no support to the theory that psychosocial stress contributes to relapse of breast cancer.     

Carcinoembryonic Antigen in Management of Colorectal Carcinoma

Carcinoembryonic antigen (C.E.A.) estimation has been used in the preoperative assessment of colorectal carcinoma patients and has been shown to give a useful guide to the presence of metastatic disease and ultimately to a poor prognosis if the serum concentration is 100 ng/ml or more. C.E.A. has been shown to be a more reliable index of tumour spread than either clinical examination or serum alkaline phosphatase estimation. Raised C.E.A. levels of less than 100 ng/ml do not, however, necessarily imply a poor prognosis. Routine C.E.A. estimation may have a valuable role in the assessment of the colorectal cancer patient by identifying those likely to benefit from postoperative chemotherapy.The test has also been assessed in a group of patients attending cancer follow-up clinics after radical resection of a colorectal tumour. Raised C.E.A. occurred in most of those developing recurrent disease, and in several patients a rising C.E.A. level preceded clinical or biochemical evidence of recurrence. C.E.A. estimation is a superior guide and of clinical importance when applied to the follow-up of the colorectal cancer patient.     

Clinical significance of serum thyroglobulin and antithyroglobulin antibody in differentiated thyroid cancer after thyroid ablation

Serum thyroglobulin (Tg) is a suitable marker for differentiated thyroid carcinoma following total thyroid ablation. Between 1998 and 2003, serum samples from 715 papillary and 179 follicular tumor patients treated with total/nearly total thyroidectomy and radioiodine ablation therapy were collected. According to the "Guidelines for Oncotherapy in Hungary", serum Tg, antithyroglobulin antibody (TgAb), TSH and FT4 levels were measured in periods of 3 months following the first treatment and of 6 months after 2 years. In the present work the prognostic value of Tg and TgAb data of cancer patients with hormone substitution therapy were evaluated individually and retrospectively. Serum Tg and TgAb concentrations were measured with a highly sensitive immunoradiometric (IRMA) method, and with a second generation, broad epitope specificity competitive radioimmunoassay, respectively. TSH levels determined by fourth generation LIAISON kit were in a range of 0.05-0.10 mIU/L. Accuracy of measuring of Tg <1 ng/ml made it possible to select the low cut-off level (Tg <2 ng/ml) following total thyroidectomy. In the predominant part of TSH-suppressed patients (746/774, 96%) the serum Tg concentration was below the cut-off level of 2 ng/ml. The sensitivity of Tg determination in 59 TSH-suppressed thyroid cancer patients with lung and bone metastases was as high as 86 to 100%. On the contrary, the number of false negative data was high in cases with lymph node metastases of papillary cancer, and sensitivity did not exceed 62%. Specificity and sensitivity of Tg in TgAb negative patients were 91 to 100%. Based on our results it could be concluded that measuring of Tg and TgAb, using a current IRMA method and a second generation RIA kit, proved to be effective tools for the postoperative monitoring of differentiated thyroid tumours. It has to be noted that determination of TgAb is highly recommended for the adequate interpretation of serum Tg levels. Persistently high and/or increasing serum TgAb concentration with low Tg result had a diagnostic value during the follow-up and can be connected with the recurrence or persistence of the differentiated thyroid cancer.     

Hypertriglyceridemia Is a Potential Preoperative Predictor for Biochemical Recurrence after Radical Prostatectomy

Objectives

Many previous studies have suggested that the outcome of prostate cancer (PCa) may be closely related to abnormal lipid metabolism. Therefore, in this study, we evaluated the preoperative lipid profiles of patients with clinically localized prostate cancer (PCa) who underwent radical prostatectomy (RP), with particular emphasis on the relationship between these profiles and biochemical recurrence (BCR).

Patients and Methods

We evaluated 715 consecutive men with clinically localized PCa who underwent RP at our institution between January 2011 and December 2013. We defined hypertriglyceridemia as a fasting serum triglyceride (TG) level greater than 200 mg/dL. We used the Kaplan—Meier method to predict BCR-free survival and applied the log-rank test to determine the statistical significance between survival curves. Cox proportional hazard ratio (HR) models were used to identify the significant predictors of BCR according to clinicopathological variables.

Results

Of 663 patients who underwent RP for clinically localized PCa, 66 (10.0%) showed BCR during a median follow-up period of 21 months. Patients without BCR had higher levels of serum TG, and patients with hypertriglyceridemia were significantly more likely to achieve BCR-free survival in the Kaplan—Meier analysis (log-rank test, P = 0.009). In the multivariable analysis, the presence of hypertriglyceridemia (HR 0.22), pathologic Gleason score (≥8; HR 2.85), pathologic T stage (≥pT3; HR 3.44), and a positive surgical margin (HR, 2.39) were still significant BCR predictors.

Conclusions

We found that preoperative hypertriglyceridemia was associated with a lower risk of BCR after RP in patients with clinically localized PCa. Our results could help to clarify the currently conflicting evidence on the relationship between serum lipid profiles, particularly the presence of hypertriglyceridemia, and the risk of BCR in PC a patients after surgery.
