Late relapse of testicular cancer: Recurrence after 24 years and treatment with chemotherapy alone

Late relapse of testicular cancer, defined as >2 years interval between initial treatment and recurrence, is a rare disease with the incidence rate of 2.6%. Due to its chemoresistant features, treatment options of late relapses are controversial while surgical approach and cisplatin-based chemotherapies can be considered. We report here a patient with nonseminomatous germ cell tumor who experienced relapse 24 years after his first diagnosis. After detecting left supraclavicular lymphadenopathy and absence of any other malignant lesion in positron emission tomography-computerized tomography, patient was treated with three cycles of VeIP regimen (vinblastine/ifosfamide/cisplatin). Second complete response to this treatment was achieved with chemotherapy alone.

Platelet to lymphocyte ratio as a new prognostic for patients with metastatic renal cell cancer

AIM

The objective of this study was to evaluate the blood platelet-lymphocyte ratio (PLR) for its prognostic value in patients with metastatic renal cell cancer (RCC).

METHODS

We retrospectively reviewed 100 patients diagnosed with metastatic RCC previously treated with tyrosine kinase inhibitors from three centers. We assessed the prognostic value of pretreatment PLR and other clinical and laboratory parameters based on univariate and multivariate analyses.

RESULTS

Median progression-free survival (PFS) was 7.3 months and median overall survival (OS) was 15.3 months. Multivariate analysis revealed that PFS is significantly affected by ECOG PS (P = 0.047), PLR (P = 0.029) and calcium level (P = 0.023). Median PFS was 13.9 versus 5.3 months in patients with PLR ≤ 210 versus PLR > 210 (log rank; P = 0.001). Median OS was 25.9 versus 10.9 months with PLR ≤ 210 versus PLR > 210 (log rank; P = 0.013).

CONCLUSIONS

This study shows that increased pretreatment PLR is an independent prognostic indicator in patients with metastatic RCC who use tyrosine kinase inhibitors.

Severe liver dysfunction and safe use of 5-fluorouracil leucovorin and oxaliplatin in one patient with metastatic colorectal carcinoma

The liver is the most frequent site of metastases in colorectal cancer. Commonly used anticancer drugs in colorectal cancer are 5-fluorouracil, oxaliplatin and irinotecan 5-fluorouracil (5-FU) and oxaliplatin have very few numbers of studies that support their safety in hepatic dysfunction, but pharmacokinetic studies of anticancer drugs focused on the single-agents; however, there is lack of data about drug combinations such as 5-fluorouracil leucovorin and oxaliplatin (FOLFOX) and 5-fluorourocil, leucovorin and irinotecan (FOLFIRI) regimens. We demonstrated one patient with colorectal cancer and severe liver dysfunction secondary to hepatic metastases. Laboratory investigation on admission showed total bilirubin 22.5 mg/dl, alkaline phosphatase 1137 IU/l, aspartate amino transferase 254 IU/l, alanine aminotransferase 164 IU/l and carcinoembryonic antigen levels 863 ng/ml. We initiated a 5-FU/oxaliplatin-based combination chemotherapy. Our data supports the safety and feasibility of FOLFOX regimen in patients with severe liver dysfunction secondary to liver metastases of colorectal cancer.

Preoperative versus postoperative chemoradiotherapy in stage T3, N0 rectal cancer

BACKGROUND

The study populations of previous preoperative chemoradiotherapy (pre-CRT) studies have consisted of mixed clinical stages, such as cT3-cT4 and/or cN positive. For this reason, it has not been possible to demonstrate whether pre-CRT is of benefit for individual subgroups.

METHODS

The medical records of 137 rectal cancer patients with clinical stage T3, N0 disease who received either pre-CRT or postoperative chemoradiotherapy (post-CRT) between 2002 and 2011 were retrospectively analyzed. The regimen of pre-CRT consisted of slow fluorouracil (5FU) infusion and that of post-CRT consisted of bolus 5FU and leucovorin concurrent with radiation.

RESULTS

Following pre-CRT, significant downstaging was achieved. However, administration of pre-CRT did not influence the type of surgical resection in tumours ≤5 cm distant from the anal verge (p = 0.14). Pathological complete response was achieved in 16 % of the patients in the pre-CRT group. The local recurrence rate (LRR) at 5 years was 5.7 % in the pre-CRT and 11.1 % in the post-CRT groups (p = 0.04). The distant recurrence rate (DRR) at 5 years was 76 % and 77 % in the pre-CRT and post-CRT groups, respectively (p = 0.1). Overall survival was similar in two groups (74.8 % vs. 75.3 %, p = 0.3).

CONCLUSIONS

The treatment of stage T3, N0 rectal cancer patients with pre-CRT followed by surgery decreased LRR, but did not improve DRR or OS as compared with surgery followed by post-CRT in our patient cohort.
