Extrapulmonary small cell carcinoma: multimodality treatment results.

Aims and Background Extrapulmonary small cell carcinoma is a distinct entity that can occur in many sites, and it is pathologically similar to small-cell lung cancer. We report the results of a retrospective study of a multimodality treatment of 16 consecutive patients with a diagnosis of extrapulmonary small-cell carcinoma. Methods Primary tumor site was prostate in 2, gallbladder in 2, uterine cervix in 2, liver in 2, endometrium in 1, epididymis in 1, colon in 1, larynx in 1, breast in 1, and unknown primary tumor in 3 patients. Patients’ ages ranged from 19 to 79 years (median, 62). Nine patients had limited and 7 had extensive disease. Histologically, 14 were pure extrapulmonary small-cell carcinoma and 2 were mixed with squamous-cell carcinoma. Results Curative surgery was attempted in 8 patients. Seven patients received local-regional adjuvant radiotherapy. All patients, except the one with a breast primary, were treated with chemotherapy (mostly platinum-based regimens). Overall survival for all patients was 41% and 11% at 2 and 5 years, respectively (median survival, 14 months). Median survival for patients with limited disease was 25 months compared to 12 months for patients with extensive disease (P = 0.05). Conclusions Treatment results for extrapulmonary small-cell carcinoma are comparable to those of small-cell carcinomas of the lung. Extent of disease is a significant prognostic factor for survival.

The association between individual attachment patterns, the perceived social support, and the psychological well-being of Turkish informal caregivers.

Background: This study aimed to investigate the relations among the psychological well‐being (i.e. depression and state/trait anxiety levels), attachment patterns (i.e. secure, ambivalent, avoidant), and the perceived social support from family/friends/significant others of caregivers of cancer patients in Turkey.

Relation of Neuroendocrine Cells to Transforming Growth Factor-Alpha and Epidermal Growth Factor Receptor Expression in Gastric Adenocarcinomas: Prognostic Implications

The presence of neuroendocrine (NE) cells in gastric adenocarcinoma (GCa) is well documented, however, their significance is controversial. There is no evidence in the literature concerning the possible effect of these cells on the expression of TGF-a and EGFR, which are believed to confer growth advantage to tumor cells. 101 partial or total gastrectomy specimens from patients operated for conventional gastric adenocarcinoma were included in the study. In each case immunohistochemistry was performed on sequential tissue sections for chromogranin A (ChrA), TGF-a and EGFR. Samples were graded based on the number of ChrA-positive cells (0–3). TGF-a and EGFR expressions were evaluated according to both the intensity (0–2) and quantification of the positively stained areas (0–3). Follow-up data was available in 54 patients. Twenty-seven patients died of disease, while 27 patients were alive with a follow-up of at least 15 months. ChrA expression was detected in 54.4% of the tumor specimens. TGF-a was stained positively in 42.6% and EGFR in 49.5% of the cases. NE cells in GCa was related to TGF-a (p<0.0001) and EGFR expression (p<0.05), and TGF-a/EGFR coexpression (p<0.001). Among histopathologic variables, the presence of NE cells was significantly related to grade, stage and lymph node status. Although the presence of NE cells had no effect on survival, the expression of EGFR (p<0.0001) and TGF-a (p=0.002) were related to survival. The results of our study suggest that the presence of NE cells may have an effect on the expression of TGF-a and EGFR in GCa, and the autocrine mechanism between TGF-α and EGFR plays an important role in the prognosis of gastric carcinoma.

Clinical Outcome of Turkish Metastatic Breast Cancer Patients with Currently Available Treatment Modalities - Single Center Experience

BACKGROUND Breast cancer is the most common malignancy and the second leading cause of cancer-related death among women in the developed countries. Despite advances in screening, improved local therapies and adjuvant systemic treatments, median survival of metastatic breast cancer patients (MBC) is in the range of 2-3 years at most. We aimed to investigate whether the prognostic factors and therapeutic responses of our Turkish patients are similar to those in the literature. MATERIALS AND METHODS We reviewed the medical records of MBC patients who had been treated in our institution between 1999-2009 and analyzed their clinicopathological features and survival outcomes retrospectively. RESULTS A hundred and sixty patients were included. Median age was 47 (23-82), median follow up was 24 (2-186) months. At the time of diagnosis 59% of patients were under the age of 50 and 46% were postmenopausal. The majority (37%) had multiple sites of metastases. Forty percent received endocrine therapy and 40% chemotherapy as first line metastatic treatment. Thirty (20%) patients were treated with molecular targeting agents like trastuzumab, lapatinib and sunitinib, frequently combined with a chemotherapy agent. Five-year overall survival (OS) was 32% and median OS was 38 months for the whole group. Five year progression free survival (PFS) was 10% and median PFS was 10 months. Menopausal status, hormone receptor expression and disease free status had a significant impact on overall survival in the multivariate analysis (p 0.018, p 0.018 and p:0.003, respectively). CONCLUSIONS All our patients were treated with the modern oncologic therapies recommended by the international guidelines. From our data, MBC patients live up to 3-4 years, indicating that further improvement beyond that requires development of new treatment modalities. The survival outcomes of our patients were consistent with the data reported in the literature.

Smoking Habits of Relatives of Patients with Cancer: Cancer Diagnosis in the Family is an Important Teachable Moment for Smoking Cessation

BACKGROUND In this study we aimed to determine the rate and habitual patterns of smoking, intentions of cessation, dependence levels and sociodemographic characteristics of relatives of patients with a diagnosis of cancer. MATERIALS AND METHODS This study was designed by the Turkish Oncology Group, Epidemiology and Prevention Subgroup. The relatives of cancer patients were asked to fill a questionnaire and Fagerstrom test of nicotine dependence. RESULTS The median ages of those with lower and higher Fagerstrom scores were 40 years and 42 years, respectively. We found no evidence of variation between the two groups for the remaining sociodemographic variables, including the subjects medical status, gender, living in the same house with the patient, their educational status, their family income, closeness to their cancer patients or spending time with them or getting any help or wanting to get some help. Only 2% of the subjects started smoking after cancer was diagnosed in their loved ones and almost 20% of subjects had quit smoking during the previous year. CONCLUSIONS The Fagerstrom score is helpful in determining who would be the most likely to benefit from a cigarette smoking cessation program. Identification of these people with proper screening methods might help us to pinpoint who would benefit most from these programs.

Non-Urothelial Bladder Cancer: Comparison of Clinicopathological and Prognostic Characteristics in Pure Adenocarcinoma and Non-Bilharzial Squamous Cell Carcinoma of the Bladder

Objectives: The clinicopathological characteristics, treatment modalities, and effects on the prognosis of pure squamous cell carcinoma (SqCC) and adenocarcinoma (AC) were evaluated. Materials and Methods: 86 patients with pure SqCC and AC bladder cancer were evaluated retrospectively. Results: Of the 86 patients, 51 had SqCC and 35 had AC. No differences in clinicopathological characteristics were observed between patients with AC and SqCC, except for the prevalence of T4 disease (28.6% vs. 51.0%, respectively). In multivariate analysis, older age, stage IV disease, and Eastern Cooperative Oncology Group (ECOG) performance status (> 2) were predictive of a poor overall survival (OS). The median OS was significantly longer for stage I-III patients (82.9 months) treated with surgery ± chemotherapy (CT) ± radiotherapy (RT) than for those treated with transurethral resection ± CT ± RT (24.3 months) (P = 0.007). The median OS of patients with SqCC and AC who were given platinum-based CT for metastasis was 7.7 and 30.3 months, respectively. Conclusions: Advanced age, stage IV disease, and poor ECOG performance status were factors associated with a poor prognosis. Surgery ± CT ± RT resulted in significantly better OS, except in stage IV disease. Patients with metastatic AC had better response rates with platinum-based CT.

Cardiac troponin T for early detection of cardiotoxicity in breast cancer patients treated with epirubicin

The aim of the study was to investigate the role of cTnT for the prediction of long term cardiac dysfunction after epirubicin-containing adjuvant chemotherapy for breast cancer. The study group comprised of 45 patients (all female; mean age 48 ±8 years), treated with epirubicin-containing adjuvant chemotherapy for stage 2 and stage 3 breast cancer. Patients received either 4 cycles of cyclophosphamide plus epirubicin (90 mg/m2) (n=23; stage 2 breast cancer) or 6 cycles of cyclophosphamide plus epirubicin (75 mg/m2) plus fluorouracil (n=18; stage 3 breast cancer). Venous blood samples were drawn, before and 72 hours after, every cycle of chemotherapy for the measurement of cTnT. Cardiac assessment was carried out at baseline and 1 year after chemotherapy by clinical evaluation, electrocardiography, radio-nuclide ventriculography (RNV) and transthoracic echocardiography. All patients remained free of clinical heart failure during the study period. In 26 patients (63%), cTnT was elevated after chemotherapy. Mean left ventricular ejection fraction, assessed by RNV at baseline and one year after chemotherapy, were 61±8% and 56±7% (p<0.0001). The sensitivity and specifity of cTnT for the detection of left ventricular systolic dysfunction at one year were 69% and 39% respectively. Echocardiographic examinations at baseline and one year after chemotherapy revealed a significant decrease in E/A ratio from 1.15±0.3 to 0.9±0.2 in cTnT positive patients, suggesting diastolic dysfunction. In conclusion, elevated serum cTnT levels after epirubicin-containing adjuvant chemotherapy for stage 2 and stage 3 breast cancer, predict future cardiac dysfunction with moderate sensitivity and poor specificity.
