Outcomes of surveillance versus adjuvant chemotherapy for patients with stage IA and IB nonseminomatous testicular germ cell tumors.

BACKGROUND: Currently, it is accepted that risk assessment of clinical stage I (CS I) nonseminomatous germ cell tumors (NSGCT) patient is mainly dependent on the presence of lymphovascular invasion (LVI). Initial active surveillance, adjuvant chemotherapy and retroperitoneal lymph node dissection (RPLND) are acceptable treatment options for these patients, but there is no uniform consensus. The purpose of this study was to compare outcomes of active surveillance with adjuvant chemotherapy. METHODS: A total of 201 patients with CS I NSGCT after orchiectomy were included. Outcomes of active surveillance and adjuvant chemotherapy were retrospectively analyzed. The prognostic significance of risk factors for survival and relapse was evaluated. RESULTS: Of the 201 patients, 110 (54.7%) received adjuvant chemotherapy, while the remaining 91 patients (45.3%) underwent surveillance. Relapses were significantly higher for patients underwent surveillance compared to adjuvant chemotherapy group (18.3 vs. 1.2%, p < 0.001). The 5-year relapse-free survival (RFS) rate for patients who were treated with adjuvant chemotherapy was significantly better than those of patients underwent surveillance (97.6 vs. 80.8%, respectively; p < 0.001). Univariate analysis showed that the presence of LVI (p = 0.01) and treatment option (p < 0.001) were prognostic factors for RFS and pT stage (p = 0.004) and invasion of rete testis (p = 0.004) and the presence of relapse (p < 0.001) were significant prognostic factors for OS. Multivariate analysis revealed that the treatment strategy was an independent prognostic factor for RFS (p < 0.001, HR 0.54). A logistic regression analysis demonstrated that treatment options (p = 0.031), embryonal carcinoma (EC) >50% (p = 0.013) and tumor diameter (p = 0.016) were found to be independent factors for predicting relapse. CONCLUSIONS: Our results indicate that adjuvant chemotherapy is associated with improved RFS compared with surveillance for CS I NSGCT patients. Moreover, the treatment strategy is an important prognostic indicator for RFS and a predictive factor for relapse. Although adjuvant chemotherapy seems to be a suitable treatment for patients with risk factors for relapse, surveillance is still preferred management option.

Treatment preferences in stage IA and IB testicular seminoma: multicenter study of Anatolian Society of Medical Oncology.

BACKGROUND: Approximately 75 % of patients with testicular seminoma present with stage I disease, and the probability of long-term survival approaches 100 %. However, the standard adjuvant treatment for stage I seminoma patients remains controversial, and there is no uniform consensus in the literature. The present study was performed to evaluate treatment preference and outcomes for men with stage I testicular seminoma. MATERIALS AND METHODS: From 1997 to 2013, 282 patients with histologically confirmed stage IA and IB testicular seminoma who underwent orchiectomy were included. The outcomes of three management options and survivals were retrospectively analyzed. The prognostic significance of risk factors for relapse on survival was evaluated by univariate and multivariate analysis; in addition, the factors predicting relapse were also evaluated by logistic regression analysis. RESULTS: Of the 282 patients with stage I seminoma, 130 (46.1) received adjuvant radiotherapy (RT), 80 (28.4 %) were treated with adjuvant carboplatin, while the remaining 72 patients (25.5 %) underwent surveillance. At the time of analysis, the median follow-up period of 38.5 months; relapses were observed in 16 patients (22.3 %) on surveillance, in one patient (1.2 %) treated with adjuvant carboplatin and in ten patients (%7.7) who received adjuvant RT. The 5-year disease-free survival (DFS) rate for patients who underwent surveillance was worse than those of patients treated with adjuvant carboplatin and RT (64.2 vs. 97.7 vs. 91.9 %, respectively; p < 0.001). However, the 5-year overall survival (OS) rate for patients on surveillance was similar compared with the adjuvant treatment groups (100 vs. 92.3 vs. 97.4 %, respectively; p = 0.44). Univariate analysis showed that only the treatment approach (surveillance vs. adjuvant carboplatin vs. adjuvant RT) for DFS (p < 0.001), invasion of the rete testis (p = 0.041) and the presence of relapse (p < 0.001) for OS were important prognostic indicators. Multivariate analysis indicated that the treatment strategy for DFS (p < 0.001, HR 0.34) was an independent prognostic factor. Furthermore, a logistic regression analysis showed that adjuvant treatment was found to be an independent factor for predicting relapse (p = 0.004, odds ratio: 0.39). CONCLUSIONS: Our results indicate that adjuvant treatment with carboplatin or RT is associated with improved DFS compared with surveillance for men with stage I testicular seminoma after orchiectomy. Moreover, the treatment strategy is an important prognostic indicator for DFS and a predictive factor for relapse. Although adjuvant treatment, especially carboplatin, seems to be a suitable treatment for patients with risk factors for relapse, surveillance is still feasible and the preferred management option after radical orchiectomy in men with stage I seminoma. More reliable predictive factors are needed to make treatment decisions.

Comparison of Oncoplastic Breast Surgery, Non-oncoplastic Breast Conserving Surgery and Mastectomy in Early Breast Cancer: A Single Center Retrospective Study.

BACKGROUND: Surgical procedures applied in the treatment of early breast cancer (EBC) to achieve satisfactory oncological results lie in a wide spectrum. There has been a major shift toward less-invasive treatments during the past decades. We compared the outcomes of oncoplastic breast surgery (OBS), non-oncoplastic breast conserving surgery (NBCS) and mastectomy in the treatment of EBC. METHODS: The records of 412 patients with EBC who underwent OBS, NBCS or mastectomy at our institution between January 2012 and June 2019 were retrospectively analyzed. Postoperative complications, local recurrences (LR) and disease-free survival (DFS) were compared between the groups. EBC patients with unilateral stage-I, IIa and IIb tumors were studied. All patients received adjuvant, targeted and/or endocrine therapy according to the tumor characteristics, followed by radiotherapy (all OBS and NBCS cases, and selected mastectomy patients). RESULTS: Postoperative complications were similar in all groups except for six fat necrosis and partial nipple-areola necrosis in two diabetic patients treated with OBS. Re-excision rate was lower in OBS (6.5%) than NBCS (8%). There was no statistical difference between the groups regarding recurrence (P=1.000) or DFS (P=0.937). CONCLUSION: OBS, NBCS and mastectomy are equally acceptable procedures in EBC in terms of both oncological and surgical aspects.

Splenomegaly in primary antiphospholipid syndrome without accompanying portal hypertension or comorbidity.

OBJECTIVE: To demonstrate the presence of splenomegaly in primary antiphospholipid syndrome (PAPS) patients without accompanying portal hypertension or comorbidity. METHODS: Twelve patients (7 women) aged 23-65 years followed upon the diagnosis of PAPS were enrolled in the study. We documented the identified causes of splenomegaly in patients with PAPS, and searched for the potential causes of splenomegaly in patients with spleen enlargement. PAPS patients with or without splenomegaly were evaluated in terms of demographic and clinical findings. RESULTS: Splenomegaly was present in 6 of the 12 patients. In these patients, there were no infections, hematological disorders, portal hypertension or malignancy that might lead to splenomegaly. The long axis of spleen was found to be in the range of 137-155 mm in patients with splenomegaly. Splenomegaly was more frequently determined in female PAPS patients. The splenomegaly group had a longer duration of disease (median 5.5 vs. 0.75 years) and a higher number of thrombotic events (median 3 vs. 1.5). The splenomegaly group was especially composed of patients who never received any anticoagulant and acetylsalicylic acid, or who used these agents irregularly for very short periods. CONCLUSION: Splenomegaly was observed in association with disease duration, frequency of thrombotic events and irregular antiaggregant or anticoagulant treatment in patients with PAPS, in the absence of comorbidity or portal hypertension.

Predictive and Prognostic Factors in Ovarian and Uterine Carcinosarcomas.

BACKGROUND: Prognostic factors and the standard treatment approach for gynaecological carcinosarcomas have not yet been clearly defined. Although carcinosarcomas are more aggressive than pure epithelial tumours, they are treated similarly. Serous/clear cell and endometrioid components may be predictive factors for the efficacy of adjuvant chemotherapy (CT) or radiotherapy (RT) or RT in patients with uterine and ovarian carcinosarcomas. Heterologous carcinosarcomas may benefit more from adjuvant CT. AIMS: We aimed to define the prognostic and predictive factors associated with treatment options in ovarian (OCS) and uterine carcinosarcoma (UCS). STUDY DESIGN: Retrospective cross-sectional study. METHODS: We retrospectively reviewed the medical records of patients with ovarian and uterine carcinosarcoma from 2000 to 2013, and 127 women were included in this study (24 ovarian and 103 uterine). Patients admitted to seventeen oncology centres in Turkey between 2000 and December 2013 with a histologically proven diagnosis of uterine carcinosarcoma with FIGO 2009 stage I-III and patients with sufficient data obtained from well-kept medical records were included in this study. Stage IV tumours were excluded. The patient records were retrospectively reviewed. Data from 104 patients were evaluated for this study. RESULTS: Age (≥70 years) was a poor prognostic factor for UCS (p=0.036). Pelvic±para aortic lymph node dissection did not affect overall survival (OS) (p=0.35). Macroscopic residual disease was related with OS (p<0.01). The median OS was significantly longer in stage I-II patients than stage III patients (p=0.03). Adjuvant treatment improved OS (p=0.013). Adjuvant radiotherapy tended to increase the median OS (p=0.075). However, this tendency was observed in UCS (p=0.08) rather than OCS (p=0.6).Adjuvant chemotherapy had no effect on OS (p=0.15).Adjuvant radiotherapy significantly prolonged the median OS in patients with endometrioid component (p=0.034). A serous/clear cell component was a negative prognostic factor (p=0.035). Patients with serous/clear cell histology for whom adjuvant chemotherapy was applied had significantly longer OS (p=0.019), and there was no beneficial effect of adjuvant radiotherapy (p=0.4). Adjuvant chemotherapy was effective in heterologous tumours (p=0.026). In multivariate analysis, the stage and chemotherapy were prognostic factors for all patients. Age was an independent prognostic factor for UCS. However, serous/clear cell histology and radiotherapy tended to be significant prognostic factors. CONCLUSION: The primary location, the histological type of sarcomatous and the epithelial component may be predictive factors for the efficacy of chemotherapy or radiotherapy in UCS and OCS.

Protective Role of Selenium and High Dose Vitamin E against Cisplatin - Induced Nephrotoxicty in Rats.

BACKGROUND: Cisplatin (CDDP) is one of the most active cytotoxic agents in the treatment of cancer. We investigated the effect of selenium (Se) with high dose vitamin E (VE) administration to prevent CDDP-induced nephrotoxicity in rats. MATERIALS AND METHODS: In this study, 40 female Wistar rats were randomly divided into five equal groups. The first group, which served as the control, was administered physiological saline (2.5 cc/day, 5 days) intraperitoneally (IP), while group A was administered cisplatin (6 mg/kg BW/ single dose) plus physiological saline IP. Groups B, C, D received IP five doses of Se (1.5 mg/kg BW), and a high dose of VE (1000 mg/kg BW) (Se-VE) in combination before, simultaneously, and after CDDP, respectively. The rats were sacrificed five days after CDDP administration. Plasma malondialdehide (MDA), glutathione peroxidase (GSH-Px), reduced glutathione (GSH), catalase, urea, creatinine levels, renal histopathological changes were measured. RESULTS: The histopathological injury score, plasma levels of MDA, urea, creatinine were found to increase in group A compared to the control (p<0.05), while plasma levels of GSH-Px, GSH and catalase decreased (p<0.05). In contrast, plasma levels of MDA decreased (p<0.05) in groups B, C, D, which were treated with Se- VE, whereas levels of GSH-Px, GSH were found to increase only for group D (p<0.05). Plasma urea, creatinine levels improved in the treatment groups compared to group A (p<0.001). Histopathological changes caused by CDDP were also significantly improved after Se-VE treatment (p<0.05). CONCLUSIONS: Oxidative stress increases with CDDP-induced nephrotoxicity in rats. Se-VE supplementation might thus play a role in the prevention of CDDP-induced nephrotoxicity in patients.

Efficiency and side effects of sorafenib therapy for advanced hepatocellular carcinoma: a retrospective study by the anatolian society of medical oncology.

BACKGROUND: Inoperable and metastatic hepatocellular carcinoma (HCC) is associated with a poor prognosis and low chemotherapeutic efficiency. Sorafenib is an oral multi-kinase inhibitor exerting its effects via the RAF/ MEK/ERK pathway, vascular endothelial growth factor receptor (VEGFR) and platelet derived growth factor receptor beta (PDGFR-ß) tyrosine kinases. Randomized studies have shown a significant contribution of sorafenib to life expectancy and quality of life of cancer patients. The aim of the present study is to evaluate the efficacy and side effects of sorafenib therapy in Turkey. MATERIALS AND METHODS: Data for 103 patients (82 males, 21 females) receiving sorafenib therapy in 13 centers from February 2008 to December 2012 were evaluated. Median age was 61 years and median ECOG performance status was 1 (range: 0-2). 60 patients (58%) had hepatitis B, 15 patients (15%) had hepatitis C infection and 12 patients (12%) had a history of alcohol consumption. All of the patients had Child scores meeting the utilization permit of the drug in our country (Child A). RESULTS: A total of 571 cycles of sorafenib therapy were administered with a median of four per patient. Among the evaluable cases, there was partial response in 15 (15%), stable disease in 52 (50%), and progressive disease in 36 (35%). Median progression-free survival was 18 weeks and median overall survival was 48 weeks. The dose was reduced only in 6 patients and discontinued in 2 patients due to grade 3-4 toxicity, 18 patients (17%) suffering hand-foot syndrome, 7 (7%) diarrhea, and 2 (2%) vomiting. CONCLUSIONS: This retrospective study demonstrated better efficacy of sorafenib therapy in patients with advanced HCC compared to the literature while progression-free survival and overall survival findings were comparable. The side effect rates indicate that the drug was tolerated well. In conclusion, among the available treatment options, sorafenib is an efficient and tolerable agent in patients with inoperable or metastatic HCC.
