RESUMO
PURPOSE: The predictive and prognostic value of cheap, easily accessible and commonly available complete blood count parameters has already been studied in a variety of cancers. In the present study, we aimed to investigate the association between pretreatment platelet/lymphocyte ratio (PLR) and metastatic gastric cancer. METHODS: The records of 228 patients dating from January 2010 to June 2014 were retrospectively evaluated. Patients who had undergone radical (N=157) or palliative gastrectomy (N=71) for metastatic gastric cancer were included and divided into two groups according to stage (early-advanced) and metastasis (absence-presence) status, and PLR values were compared. RESULTS: 38 (16.6%) of 228 patients had early gastric cancer (non metastatic cases). PLR values of advanced gastric cancer (not including metastatic cases) were significantly higher compared to early gastric cancer (231.6±107.45 and 160.3±71.5, respectively; p<0.001). Seventy one (31.1%) of 228 patients had distant metastasis. PLR values of metastatic gastric cancer were significantly higher than in non-metastatic gastric cancer (251.0±94.8 and 192.7±88.8, respectively; p<0.001). Logistic regression analysis showed that PLR was an independent predictive factor for tumor burden in both stage and metastasis groups (p<0.001 and p=0.003, respectively). Also, in correlation analysis, PLR showed mild correlation with stage and metastasis groups (r=0.291 and r=0.299, respectively). CONCLUSIONS: Pretreatment PLR values were correlated with tumor burden, and most higher values were detected in metastatic disease. Our findings may be useful, especially in the decision-making for laparoscopic staging in patients who have no radiological evidence of metastatic disease.

BACKGROUND/OBJECTIVE: The aim of this study was to evaluate with electromyography (EMG) the effect of lateral pectoral nerve sparing technique (LPNST) and radiotherapy (RT) on the lateral pectoral nerve (LPN) in patients applied with modified radical mastectomy (MRM). METHODS: The study included 66 patients who underwent MRM surgery. The patients were separated into 2 groups as those applied with LPNST and those who underwent standard surgery (Control group). Within these 2 groups, patients were again separated as those who received or did not receive RT. The EMG evaluations were made by a neurology specialist blinded to the patient groups. RESULTS: The mean age of the patients was 53.3 ± 10.6 years. Standard surgery was applied to 33 (50%) patients and LPNST to 33 (50%) patients, RT was applied to 32 (48.5%) patients and not to 34 (51.5%) patients. In the EMG evaluation, latency was 2.1 ms (1.4-3.2) in the LPNST and 3.7 ms (1.9-12.4) in the control (p <0.001) and amplitude values were 9650 mV (3120-36900) in the LPNST and 4780 mV (510-12.4) in the control (p <0.001). The latency values in the Control receiving and not receiving RT were 4.0 ms (1.9-12.4) and 2.6 ms (1.9-6.2) respectively (p <0.05). The latency values of the patients receiving and not receiving RT in the LPNST were 2.2 ms (1.8-3.2) and 2.0 ms (1.4-2.4) respectively (p <0.05). In the Control and LPNST Group, no significant difference was determined between receiving and not receiving RT groups in respect of amplitude values (p >0.05). CONCLUSION: The results of this study demonstrated that electromyographically the latency and amplitude values were better protected in the LPNST group. It was also seen that RT increased the formation of nerve damage in both groups.

PURPOSE: In this study, we aimed to describe the real-life practice outcomes of pertuzumab-trastuzumab-taxane (PTT) combination in visceral organ metastatic, trastuzumab-naive breast cancer (BC) patients. METHODS: This study was conducted by Turkish Oncology Group and included 317 patients' data from 36 centers. RESULTS: Median age was 51 (22-82). Median PFS was 28.5 months, while median OS was 40.3 months. Patients with brain metastases (n: 13, 4.1%) had worse PFS (16.8 m vs. 28.5 m; p = 0.002) and OS (26.7 m vs. 40.3 m; p = 0.009). Patients older than 65 years of age (n: 42, 13.2%) had significantly lower OS results (19.8 m vs. 40.3 m; p = 0.01). Two hundred sixty-eight patients (86.7%) received docetaxel while 37 patients (11.7%) received paclitaxel. PFS and OS were similar between taxane groups. In eight patients (2.5%), 5-40% ejection fraction decrement from baseline was detected without any clinical sign of heart failure. CONCLUSIONS: Our RLP trial included only visceral metastatic, trastuzumab-naïve BC patients including cases with brain involvement who received PTT combination in the first-line treatment. Regardless of negative prognostic characteristics, our results are in parallel with pivotal trial. Further strategies for brain metastasis should be developed to improve outcomes despite encouraging results with PTT treatment. Taxane selection can be personalized and endocrine maintenance may further improve outcomes after taxanes were discontinued. To our knowledge, this is the largest scale real-life clinical practice study of pertuzumab-trastuzumab-taxane therapy to date.

BACKGROUND: In Muslim majority countries (MMC) opioid use for pain management is extremely low. The underlying factors contributing to this are not well defined. AIM: The aim of this study was to survey the attitudes of cancer patients towards morphine use for pain management in a MMC and identify the factors that influence patient decisions to accept or refuse morphine as treatment for cancer pain. SETTINGS/PARTICIPANTS: Patients were questioned whether they had pain or not, the severity and the medications for pain management. Questions included what type of medication they thought morphine was, whether or not they would be willing to take morphine if recommended for pain management and the basis for their decision if they were against morphine use. RESULTS: Four hundred and eighty-eight patients participated in the study. Some 50% of the patients who refused morphine use and 36.8% of the patients who would prefer another drug, if possible, identified fear of addiction as the basis for their decision. Reservation of morphine for later in their disease was the case for 22.4% of the patients who refused morphine use. Only 13.7 % of the patients refusing morphine and 9.7% of the patients who preferred another drug, if possible, cited religious reasons as the basis for this decision. CONCLUSIONS: Identifying the underlying factors contributing to low opioid use for pain management in MMC is important. Once the underlying factors are identified, all efforts should be taken to overcome them as they are barriers to improving patient pain management.
