The effect of small-molecular-weight heparin added to chemotherapy on survival in small-cell lung cancer - A retrospective analysis.

Aims and Background: Small cell lung cancer (SCLC) is a chemotherapy-responsive tumor and associated with alterations in the coagulation system. Addition of low-molecular-weight heparin (LMWH) to combination chemotherapy (CT) had resulted in increase in survival. The present retrospective trial was designed to determine whether the duration of dalteparin usage has an effect on progression and survival. Materials and Methods: The medical records of 67 patients with SCLC who were given cisplatin-etoposide and concomitant LMWH (dalteparin) was evaluated retrospectively. Results: Median follow-up of patients was 11.3 months. Outcome: 10.6% complete response, 3.0% good partial response, 36.4% partial response, 10.6% stable disease, and 39.4% progressive disease. Side-effects were seen in 40.3% of the patients. Median dalteparin duration was 6,1 months. According the duration of dalteparin patients were grouped in three: who took dalteparin less than 4 months (Group A), 4-6 months (Group B) and more than 6 months (Group C). Mean overall survival (OS) in Group A was 6.5 months, in Group B 11.8 months, and Group C 14.6 months. Mean OS in Group B and C were statistically significantly (P < 0.001) longer than Group A, between Group B and C there was not any significant difference (P = 0.037). Mean progression free survival (PFS) was 9 months. Conclusions: The CT plus LMWH minimum 4 months long is well-tolerable, and may improve PFS and OS in patients with SCLC. For treatment of patients with SCLC CT plus LMWH may be considered as effective future-therapy, and further multi-centre randomised prospective clinical trials must be done to determine the new standard treatment approach for SCLC.

D-dimer is a marker of response to chemotherapy in patients with metastatic colorectal cancer.

PURPOSE: D-dimer, LDH and tumor markers are usually overexpressed in colorectal carcinomas (CRC). Our purpose was to assess the prognostic role of D-dimer, lactate dehydrogenase (LDH), CEA, CA19-9 and CA72-4 in patients with metastatic CRC treated with XELOX chemotherapy. METHODS: Thirty-eight CRC patients who had evidence of distant metastasis were enrolled in the study and blood samples were taken before chemotherapy for estimation of the tumor markers CEA, CA19-9 and CA72-4, and for D-dimer and LDH. Patients were randomized into 3 groups: those with partial response (PR), stable disease (SD), and progressive disease (PD) according to their clinical and radiologic evaluation after 3 cycles of XELOX chemotherapy. All parameters were reevaluated after the 3rd cycle of chemotherapy. RESULTS: Eighteen patients (47.3%) achieved PR, 10 (26.3%) SD, and 10 (26.3%) showed PD. After 3 cycles of XELOX CEA (20.55 vs 11.97 ng7sol;ml; p=0.002), LDH (357.50 vs 214.0 U7sol; lt; p=0.001) and D-dimer (1.56 vs 1.17 µgFEU/ml; p=0.022) levels were significantly decreased in the PR group. D-dimer levels were also notably decreased (1.36 vs 0.77 µgFEU/ml; p=0.021) in the SD group. In the PD group a considerable increase was seen in CA 19-9 (119.5 vs 243.09 U/ml; p=0.025), CA 72-4 (5.18 vs 25.8 U/ml; p=0.036) and D-dimer levels (1.77 vs 1.88 µgFEU/ml; p=0.012). CONCLUSION: This study demonstrated that D-dimer, LDH and tumor markers can be helpful in determining CRC prognosis in patients with metastatic disease. D-dimer, LDH and tumor markers provided unique prognostic information in advanced CRC patients.

The effect of being overweight on survival in patients with gastric cancer undergoing adjuvant chemoradiotherapy.

The aim of this study was to examine the effect of being overweight on survival in patients with gastric cancer undergoing adjuvant chemoradiotherapy and chemotherapy. In this study 152 patients were evaluated. Radiotherapy dose was 45 Gy given in 5 weeks. 5-FU 425 mg/m(2) and folinic acid 20 mg/m(2) were administered weekly during the radiotherapy and four cycles with 4-week intervals as consolidation chemotherapy after radiotherapy. Patients were assigned into two groups according to their body mass index: overweight (body mass index ≥25 kg/m(2)) and normal weight (body mass index <25.0 kg/m(2)). The median overall survival was 39 months vs. 18 months and median disease-free survival was 27 months vs. 13 months in the overweight and normal-weight groups respectively (P = 0.004 and P = 0.006 respectively). The 5-year survival was better in the patients with overweight than those with normal weight (42% vs. 17%; P = 0.004). The overall survival was significantly better with being overweight and early pathological stage (P = 0.016 and P = 0001 respectively). Overall survival, disease-free survival and long-term survival in patients with gastric cancer undergoing adjuvant treatment were better in overweight than normal-weight patients. Moreover, it was shown that body mass index and pathological stage were associated to survival and prognosis.

Gemcitabine and cisplatin combination chemotherapy in triple negative metastatic breast cancer previously treated with a taxane/anthracycline chemotherapy; multicenter experience.

This study was aimed to establish clinical efficacy and tolerability of gemcitabine and cisplatin combination in patients with metastatic triple negative breast cancer progressing after anthracycline and taxane based chemotherapies.Thirty-three patients who were given cisplatin and gemcitabine for triple negative and metastatic breast cancer were evaluated retrospectively. A total of 141 cycles were administered with a median 4 cycles per patient. Median follow-up time was 14 months (range, 2-36 months). Objective response rate was 27.3%. Total clinical benefit of the combination was 48.4%. The estimated median progression free survival and median overall survival were 5 months and 14 months, respectively. The most common Grade 3 and 4 toxicity were neutropenia and thrombocytopenia observed in 10 (27.7%) and 9 (24.9%) patients, respectively. The combination of the gemcitabine and cisplatin after taxane/anthracycline is well tolerated and seems to be effective with acceptable toxicity profile.

Xelox (capecitabine plus oxaliplatin) as neoadjuvant chemotherapy of unresectable liver metastases in colorectal cancer patients.

Complete resection of liver metastasis may provide long term survival in patients with colorectal cancer. Increased number of studies on successful resection after neoadjuvant chemotherapy with initially unresectable liver metastasis has been reported. We evaluated retrospectively the results of 35 patients with unresectable liver only metastases from colorectal cancer treated with capecitabine plus oxaliplatin combination (XELOX). Treatment consisted of IV oxaliplatin 130 mg/m2 day 1 and oral capecitabine 1000 mg/m2 day twice daily on days 1 to 14 followed by 7 days of rest repeated every 3 weeks. After chemotherapy, 13 (37, 2 %) patients showed partial clinical response. Among them, 7 patients were considered suitable for surgery but 2 patients refused the surgery. While one of 5 patients had unresectable disease at surgery, the remaining 4 patients (11, 4 %) had a complete resection. There was one postoperative mortality due to sepsis within 2 months after surgery. Our data suggests that XELOX regimen seems to be useful in unresectable liver only metastases from colorectal cancer because of its activity, feasibility and tolerability. Further studies of XELOX in combination with bevacizumab and/ or cetuximab are warranted in this setting.

Cutaneous metastasis of endometrial carcinoma with hemorrhagic nodules and papules.

BACKGROUND: Endometrium cancer is the fourth most frequent malignancy in women. However, skin metastasis from endometrium cancer is a very rare entity. CASE: A 58-year-old multiparous woman postmenopausal for ten years presented with multiple metastatic, nodular, hemorrhagic skin lesions located at the initial surgery and radiotherapy site 14 months after the original diagnosis was made. Combination chemotherapy was instituted, but the patient died after the second cycle of chemotherapy. CONCLUSION: Although endometrial cancer is one of the most frequent malignancies in women, skin metastasis from endometrial cancer is very rare. In reported cases metastasis from endometrial cancer has been most commonly noted at the initial surgery and radiotherapy site. Therefore, the initial surgical and radiotherapy site must be examined carefully for skin metastasis.

Blastic natural killer cell leukaemia with skin involvement: a case report.

Natural killer cell leukaemia is generally accompanied by extramedullary involvement. CD4+ natural killer cell leukaemia frequently manifests with cutaneous involvement. The disease pursues a very aggressive course with no long-term survivors reported. We present a patient with CD4+ natural killer cell leukaemia with skin, bone marrow and peripheral blood involvement who is still on remission at the end of 2 years.
