Factors affecting prognosis and treatment strategies in metastatic soft tissue sarcomas: twenty years of experience.

OBJECTIVE: In this study, we aimed to reveal the general clinicopathological features, treatment features, and factors that could predict overall survival in metastatic soft tissue sarcomas, a very rare and heterogeneous disease group. PATIENTS AND METHODS: This study was a retrospective cohort study. Patients monitored with metastatic soft tissue sarcoma between January 2001 and January 2021 were evaluated retrospectively. Patients aged 18 years and over, histopathologically diagnosed with metastatic STS, and unsuitable for operations, such as local curative surgery or metastasectomy, were included in the study. RESULTS: A total of 179 patients in the metastatic stage and monitored in our center were included in the study. The median follow-up period was 8.4 months (IQR, 3.4-14.4). 58 (32.4%) patients were de-novo metastatic, and 121 (67.6%) patients developed metastasis later. The median age was 53.2 (Range: 18.8-87.6 years), and 101 (56.4%) patients were male. The most common primary location was the lower extremity (87) (48.6%). The most common histological subtypes were synovial sarcoma (38) (21.2%), pleomorphic sarcoma (37) (20.7%), and liposarcoma (26) (14.5%). The majority were grade 3 tumors (n=131, 73.2%). Having ECOG PS 2-3 (HR=2.829, 95% CI 1,667-4.800, p<0.001), having tumor grade as 3 (HR=1.748, 95% CI 1.150-2.656, p<0.009), receiving palliative chemotherapy (HR=0.294, 95% CI 0.144-0.600, p<0.001), and receiving two or more lines of chemotherapy among those palliative receivers (HR=2.505 95% CI 1.696-3.700, p<0.001) were independent predictive factors of mortality. CONCLUSIONS: Survival in metastatic soft tissue sarcoma is better in patients with good ECOG performance status, low tumor grades, and who have received palliative chemotherapy. Receiving more than one line of palliative systemic treatment for progressive disease improves survival.

Duration of anti-HER2 blockage therapy may improve survival in HER2 positive metastatic breast carcinoma patients.

PURPOSE: The duration of anti-HER2 blockage therapy in metastatic breast cancer patients is still unclear. We aimed to evaluate the effect of the anti-HER2 blockage therapy duration and other factors on survival in HER2 positive metastatic breast carcinoma (MBC) patients. METHODS: The medical records of 193 HER2 positive MBC patients, who did not have the opportunity to receive adjuvant trastuzumab therapy but had received trastuzumab in the metastatic setting were retrospectively evaluated. RESULTS: The median age at diagnosis was 45.0 years (range 21-83). Ninety-two (47.7%) patients received palliative trastuzumab < 6 months median, whereas 101 patients received trastuzumab ≥ 6 months median. The median number of trastuzumab cycles was 8 (range 1-51). Median survival after breast cancer recurrence was 31.0 months (range 24.3-37.7). The duration of trastuzumab therapy had a significant impact on the prognosis of recurrent breast cancer (22.0 vs 49.0 months, for ≤ 6 months of treatment duration, respectively; p<0.0001). Survival after breast cancer recurrence for the patients who received lapatinib plus capecitabine vs those who did not was significantly different (59 patients, p=0.005). Moreover, there was a statistically significant relationship between prolonged lapatinib plus capecitabine combination therapy and improved survival after disease recurrence (p=0.022). In the multivariate Cox regression analysis, treatment with trastuzumab > 6 months (p=0.003) was the only independent prognostic factor for survival after breast cancer recurrence. CONCLUSION: The duration of anti-HER2 blockage therapies, especially with trastuzumab, seems to improve survival of HER2-positive metastatic breast cancer patients who were not previously treated with adjuvant trastuzumab, regardless of other therapies.

ABO and Rh blood groups frequency in women with HER2 positive breast cancer.

PURPOSE: The role of genetic factors in the development of cancer is widely accepted. Data on the role of ABO blood group and Rh factor in breast cancer is inconclusive. The aim of this study was to investigate the presence of a possible association between HER2 (+) breast cancer in Turkish women and ABO blood groups and Rh factor. METHODS: In 294 female patients with HER2 (+) breast cancer, ABO blood groups and Rh factor were examined. The relationship of blood groups with age, menopausal status, and family history of cancer, estrogen receptor (ER), progesterone receptor (PR) and HER2 status of these patients was evaluated. Blood groups distribution of 22,821 healthy blood donors was also assessed and compared with the patients' blood groups distribution. RESULTS: The median patient age was 47 years (range 20-80) and 56% of the patients were premenopausal. ER and PR were positive in 50 and 60% of the patients, respectively. Overall, the ABO blood group distribution of the 294 HER2 (+) breast cancer patients was similar to that of the healthy blood donors (p=0.36). Likewise there was no correlation between blood type and ER, PR and menopausal status. Rh (-) patients had more frequent family cancer history and this difference was significant for patients with blood group B Rh (-) and O Rh (-) (p = 0.04). CONCLUSION: In the present study we didn't find any relationship between HER2 status and ABO blood group and Rh factor. However, further studies with larger number of patients are needed to establish the role (if any) of blood groups in patients with breast cancer.

Blood viscosity in patients with diffuse large B cell non-Hodgkin's lymphoma.

UNLABELLED: The aim of the study was to evaluate blood viscosity as possible marker of disease progression in patients with newly diagnosed non-Hodgkin's lymphoma (NHL). METHODS: The viscosity of blood samples from 20 patients with newly diagnosed aggressive NHL (stage I, n=7; stage II, n=4; stage III, n=7; stage IV, n=2) was analyzed using Brookfield DV-II + (USA) machine. RESULTS: Blood viscosity in NHL patients (median: 5.5+/-1.46 miliPascal) inversely correlated with lactatdehydrogenase (LDH) level, international prognostic index (IPI) score, and stage (p=0.02, r=-0.51; p=0.03, r=-0.63; and p=0.04, r=-0.45, respectively) and positively correlated with hemoglobin level (p=0.02, r=0.65)). CONCLUSION: According to our data, blood viscosity may be considered as a follow up marker in NHL patients along with LDH level or sedimentation rate.
