Prognostic role of neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, systemic immune-inflammation index, and pan-immune-inflammation value in metastatic castration-resistant prostate cancer patients who underwent 177Lu-PSMA-617.

This study is aimed to investigate the prognostic significance of inflammation indices, including neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and pan-immune-inflammation value (PIV) in metastatic castration-resistant prostate cancer (mCRPC) patients who had received lutetium labeled prostate-specific membrane antigen (177Lu-PSMA-617) therapy. Sixty-one mCRPC patients who received 177Lu-PSMA-617 treatment and followed up in Kocaeli University were included. The relationship between overall survival (OS) and progression-free survival (PFS) and clinical and laboratory parameters was analyzed by multivariate analyses. The mean age was 69.8 ±â€…6.9 years. The mean follow-up time was 53.2 ±â€…24 months. The median OS was 14 (95% CI: 8.8-18.1) and the median PFS was 10.4 (95% CI: 4.7-17.2) months. NLR ≥ 2.7, PLR ≥ 134.27, SII ≥ 570.39, PIV ≥ 408.59 were considered as elevated levels. In the multivariate analysis for OS, baseline ECOG performance score (HR: 1.92, 95% CI: 1.01-3.65, P = .046), high albümin (HR: 0.36, 95% CI: 0.16-0.82, P = .015), primary resistant total prostate-specific-antigen (PSA) (HR: 4.37, 95% CI: 1.84-10.35, P = .001), high NLR (HR: 3.32, 95% CI: 1.66-6.65, P = .001), high MLR (HR: 2.53, 95% CI: 1.35-4.76, P = .004), high PLR (HR: 2.47, 95% CI: 1.23-4.96, P = .01), and high SII (HR: 2.17, 95% CI: 1.09-4.32, P = .027) were associated with shorter OS. However, PIV was not associated with survival (P = .69). No factor other than the primer-resistant PSA could be identified as having an impact on PFS (for the PSA, HR: 4.52, 95% CI: 1.89-10.76, P = .001). In this study, pretreatment NLR, MLR, PLR, and SII demonstrate as powerful independent prognostic indices predicting survival in patients with mCRPC receiving 177Lu-PSMA-617 therapy.

A study on basic demographic and disease characteristics of cancer-diagnosed Syrian refugees treated in the border city of Turkey, Sanliurfa; a hospital-based retrospective case series study.

PURPOSE: Turkey hosts around 3 million Syrian refugees which is more than any other country in the world. Along with some other adaptation issues like cultural, language, and economic difficulties, significant problems in managing medical problems, chronic diseases like cancer in particular, have to be fixed. However, there are few studies which explore main patient and clinicopathological characteristics in Syrian refugees with cancer. The purpose of this study was to highlight the aforementioned characteristics along with management issues after cancer diagnosis of these patients. METHODS: This study was designed as a hospital-based retrospective observational case-series study of 134 Syrian refugees cancer patients between 2015 and 2017. RESULTS: The patient median age was 47.5 years (range 18- 80). Out of the 134, 102 (76.1%) were female. The most common cancer types were breast (n=57, 42.5%) and gynecological cancers (n=14, 10.4%). The majority of patients were diagnosed at advanced stage (n=60, 44.8%). There were 91 (67.9%) and 43 (32.1%) patients admitted to our center from refugee camps and staying in a house, respectively. The median follow-up was 14 months (range 1-111) and 11 (8.2%) patients died. One and two-year survival rate of the whole group were 93% and 86%, respectively. There were 12 (9%) patients with grade 3-4 hematological and non-hematological toxicities. Neutropenia was the most common grade 3-4 toxicity (n=8, 6%). The patients staying in refugee camp (n-91) or in a house (n=43) finished all planned cycles of chemotherapy with a rate of 71% (n=65) and 79% (n=34), respectively. Statistical analysis failed to show significant relationship between the staying site (either camp or house), chemotherapy compliance rate, grade 3-4 toxicities with p=0.347 and p=0.09, respectively. CONCLUSION: Our results revealed that breast cancer and gynecological cancers were the most common cancer types which are good candidates for cancer screening. Unfortunately, the majority of patients had cancer diagnosed at advanced stage. However, after diagnosis they could reach all health facilities including surgical operation, radiotherapy, and systemic chemotherapy similar to Turkish cancer patients. Therefore, our results suggested that major problem for the Syrian refugees adapting them into national screening program which may resulted that cancer diagnosis at earlier stage with high cure rate.
