RESUMEN
BACKGROUND: Lymph node metastasis is a predominant prognostic indicator in colorectal cancer. Number of lymph nodes removed surgically was demonstrated to correlate with staging accuracy and oncological outcomes. However, number of lymph nodes removed depends on uncontrolled variables. Therefore, a more reliable prognostic indicator is needed. Calculation of ratio of positive lymph nodes to total number of removed lymph nodes may be an appealing solution. MATERIALS AND METHODS: We retrospectively analyzed data of 156 Stage III colorectal cancer patients whom underwent surgery between 2008 and 2015. Patients' demographic characteristics, tumor grade, location, vascular-perineural invasion status, number of removed lymph nodes, and ratio of positive lymph nodes to number of removed lymph nodes were recorded. Spearman correlation analysis was used to determine the correlation coefficient while Kaplan-Meier method and Cox proportional hazard regression model were performed for the prediction of survival and multivariate analysis, respectively. RESULTS: Number of removed lymph nodes did not correlate with survival, but it was inversely correlated with number of positive lymph nodes. Multivariate analysis showed that ratio of removed positive lymph nodes to the total number of lymph nodes was a significant prognostic factor for survival for a ratio equal or above 0.31 was a poor prognostic indicator (108 months vs. 34 months, hazard ratio: 4.24 [95% confidence interval: 2.15-8.34]; P < 0.019). Tumor characteristics failed to demonstrate any prognostic value. CONCLUSIONS: This study showed that positive lymph node ratio (PLNR) is an important prognostic factor for Stage III colorectal cancer. Although 0.31 can be taken as threshold for "PLNR," prospective trials including larger patient groups are needed to validate its role as a prognostic indicator.

AIM OF THE STUDY: Systemic chemotherapy for patients with pancreatic cancer has limited impact on overall survival (OS). Patients eligible for chemotherapy should be selected carefully. The aim of the study was to search for prognostic factors for survival in patients with gemcitabine (Gem)-refractory or with gemcitabine and cisplatin (GemCis)-refractory advanced pancreatic cancer. MATERIAL AND METHODS: We retrospectively evaluated patients with Gem- or GemCis-refractory advanced pancreatic cancer. Sixteen potential prognostic variables were chosen for analysis in this study. Univariate and multivariate analyses were conducted to identify prognostic factors associated with survival. Univariate and multivariate statistical methods were used to determine prognostic factors. RESULTS: Multivariate analysis included the four prognostic significance factors in univariate analysis. Multivariate analysis showed that liver metastasis and second-line chemotherapy were considered independent prognostic factors for survival. CONCLUSIONS: Liver metastasis and second-line chemotherapy were identified as important prognostic factors in advanced pancreatic cancer patients refractory to treatment with Gem or GemCis. This prognostic factors may also facilitate pretreatment prediction of survival and can be used for selecting patients for treatment.
RESUMEN
Although more palliative care is necessary for terminally ill cancer patients, excess investigational tests, invasive procedures, and treatments are given instead. Between November 2009 and December 2013, six hundred and twenty-four patients with end-stage cancer who were died at inpatient setting evaluated retrospectively. Patients' characteristics, sites of tumor and metastasis, tests and invasive procedures, treatments performed in the last 2 weeks before death were collected from the hospital files and analyzed. Median age of 624 patients was 58 (range 16-96) years. More than half of the patients (370, 59.3%) were men. The most frequent cancer sites were gastrointestinal (GI) system (32.2%), lung (24.0%), and breast (11.1%). Frequent metastatic sites were liver (34.8%), bone (31.5%), lung (23.3%), and/or brain (16.9%). Causes of death were respiratory failure, infections, and/or liver failure in 49.9, 23.9, and 19.4% of patients, respectively. Radiological tests performed in the last 2 weeks before death were ultrasonography, computed tomography, magnetic resonance imaging, bone scan in 25.6, 16.3, 11.4, and 3.8% of patients, respectively. Treatments received were intravenous (i.v) serum infusion, blood transfusion, total parenteral nutrition (TPN), human albumin infusion in 55.9, 44.1, 34.9, and 9.5% of patients, respectively. Invasive procedures such as invasive pain relief, terminal sedation, and chemotherapy performed in 12.6, 4.4, and 10.0% of patients, respectively. Central venous catheter application, paracentesis, thoracentesis, and GI endoscopy were applied in 41.7, 9.8, 5.6, and 3.4% of the patients, respectively. Radiological tests, invasive procedures, TPN, and human albumin transfusion were used excessively in terminal stage cancer patients in our medical oncology inpatient clinics. Invasive pain relief and terminal sedation were still underused in our cancer clinics. There is an urgent need in developing national palliative care program to improve the understanding of end-of-life care in our medical oncology clinics.

BACKGROUND: The standard therapy for stage I rectum cancer is surgical resection. Currently, there is no strong evidence to suggest that any type of adjuvant therapy is beneficial. The risks of local relapse and distant metastasis are higher in rectal tumors. Therefore, while there is no clearly defined absolute indication for adjuvant therapy in lymph node negative colon cancers, rectum tumors that are T3N0 and higher require adjuvant treatment. Due to the more aggressive nature of rectal cancers, we explored the clinical and pathologic factors that could predict the risk of relapse in Stage I (T1-T2) disease and whether there was any progression-free survival benefit to adjuvant therapy. MATERIALS AND METHODS: This multicenter study was carried out by the Anatolian Society of Medical Oncology. A total of 178 patients with rectal cancers who underwent curative surgery between January 1994 and August 2012 in 13 centers were included in the study. Patient demographics, including survival data and tumor characteristics were obtained from medical charts. RESULTS: The median age was 58 years (range 26-85 years). Most tumors were well or moderately differentiated. For adjuvant treatment, 13 patients (7.3%) received radiotherapy alone, 12 patients (6.7%) received chemotherapy alone and 15 patients (8.4%) were given chemoradiotherapy. Median follow up was 29 months (3-225 months). Some 42 patients (23.6%) had relapse during follow up; 30 with local recurrence (71.4%) whereas 12 (28.6%) were distant metastases. Among the patients, 5-year DFS was 64% and OS was 82%. Mucinous histology and receiving adjuvant therapy were found to have statistically insignificant correlations with relapse and survival. CONCLUSIONS: In our retrospective analysis, approximately one quarter of patients exhibited either local or systemic relapse. The rates of relapse were slightly higher in the patients who had no adjuvant therapy. There may thus be a role for adjuvant therapy in high-risk stage I rectal tumors.

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.

There is very little information about breast cancer characteristics, treatment choices, and survival among elderly patients. The purpose of this multicenter retrospective study was to examine the clinical, pathologic, and biologic characteristics of 620 breast cancer patients age 70 years or older. Between June 1991 and May 2012, 620 patients with breast cancer, recruited from 16 institutions, were enrolled in the retrospective study. Patients had smaller tumors at diagnosis; only 15% of patients had tumors larger than 5 cm. The number of patients who had no axillary lymph node involvement was 203 (32.7%). Ninety-three patients (15.0%) had metastatic disease at diagnosis. Patients were characterized by a higher fraction of pure lobular carcinomas (75.3%). The tumors of the elderly patients were also more frequently estrogen receptor (ER) positive (75.2%) and progesterone receptor (PR) positive (67.3%). The local and systemic therapies for breast cancer differed according to age. An association between age and overall survival has not been demonstrated in elderly patients with breast cancer. In conclusion, the biologic behavior of older patients with breast cancer differs from younger patients, and older patients receive different treatments.

UNLABELLED: Several studies have now demonstrated that the lymph node ratio (LNR), as a superior indicator of axillary tumor burden to the number of excised nodes. While, about the prognostic value of LNR on the the survival of elderly patients is limited. The aim of this retrospective multicenter study is to evaluate the prognostic value of lymph node ratio in elderly patients with node positive breast cancer. METHODS: Onehundredeightyfour patient with operable breast cancer, recruited from 17 institutions, were enrolled into the retrospectively study. Eleven potential prognostic variables were chosen for analysis in this study. Univariate and multivariate analyses were conducted to identify prognostic factors associated with survival. RESULT: Among the eleven variables of univariate analysis, four variables were identified to have prognostic significance for Overall survival (OS): pathologic tumor size (T), No. of positive nodes (N), LNR and estrogen receptor-positive (ER). Among the eleven variables of univariate analysis, two variables were identified to have prognostic significance for Disease-free survival (DFS): N and LNR. Multivariate analysis by Cox proportional hazard model showed that T, LNR and ER were considered independent prognostic factors for OS. Furthermore, LNR was considered independent prognostic factors for DFS. CONCLUSION: In conclusion, the LNR was associated with the prognostic importance for DFS and OS in elderly patients who were administered adjuvant treatments.

BACKGROUND/AIMS: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasm of the gastrointestinal tract. In an attempt to survey the approximate incidence, clinicopathological characteristics, and immunophenotypic features of GISTs in Turkey, we conducted a clinicopathological and immunohistochemical analysis of GISTs. METHODOLOGY: Three hundred and thirty-three patients with GIST from nine institutions in Turkey were retrospectively evaluated. RESULTS: Between January 2001 and March 2011, a total of 333 patients with GISTs were included; of these, 204 (61.2%) were male and 129 (38.8%) were female. The median age was 55 years (range; 22-102 years). At the median follow-up of 26 months (range; 4-166 months), the 1-, 3- and 5-year OS rates of the 333 patients were 96.9%, 85.8% and 78.5%, respectively. The 5-year DFS rate was 40%. The 5-year OS rate and median OS time for the patients with R0 resection were significantly higher than for patients with metastatic diseases (79.7 vs. 75.7% and not reached vs. 115 months, respectively, p=0.04). CONCLUSION: Although our results should be confirmed by prospective studies, we believe that they contribute to the literature because the study included both resectable and metastatic or unresectable GIST patients and multicenter findings from Turkey.

BACKGROUND: The majority of patients with pancreatic cancer present with advanced disease. Systemic chemotherapy has limited impact on overall survival (OS) so that eligible patients should be selected carefully. The aim of this study was to analyze prognostic factors for survival in Turkish advanced pancreatic cancer patients who survived more than one year from the diagnosis of recurrent and/or metastatic disease and receiving gemcitabine (Gem) alone or gemcitabine plus cisplatin (GemCis). METHODS: This retrospective evaluation was performed for patients who survived more than one year from the diagnosis of recurrent and/or metastatic disease and who received gemcitabine between December 2005 and August 2011. Twenty-seven potential prognostic variables were chosen for univariate and multivariate analyses to identify prognostic factors associated with survival. RESULTS: Among the 27 variables in univariate analysis, three were identified to have prognostic significance: sex (p=0.04), peritoneal dissemination (p=0.02) and serum creatinine level (p=0.05). Multivariate analysis by Cox proportional hazard model showed only peritoneal dissemination to be an independent prognostic factor for survival. CONCLUSION: In conclusion, peritoneal metastasis was identified as an important prognostic factor in metastatic pancreatic cancer patients who survived more than one year from the diagnosis of recurrent and/ or metastatic disease and receiving Gem or GemCis. The findings should facilitate pretreatment prediction of survival and can be used for selecting patients for treatment.

BACKGROUND/AIMS: The efficacy and tolerability of oxaliplatin in combination with either folinic acid, fluoro-uracil (5-FU) (FOLFOX4 regimen) or capecitabine (XE-LOX regimen) was evaluated in advanced pancreatic cancer. METHODOLOGY: In this study, eighty-five patients with advanced pancreatic cancer were enrolled after failing to gemcitabine-based chemotherapy between November 2005 and August 2011. FOLFOX4 was repeated every two weeks and XELOX regimen was repeated every three weeks until either disease progression or unacceptable toxicity occurred. RESULTS: Eighty-five patients were evaluated for tumor response.Seven patients (18%) achieved a partial response with XELOX and stable disease was observed in 16 patients (41%). Eight patients (17%) achieved a partial response with FOLFOX4 and stable disease was observed in 12 patients (26%). Disease control rates were 59%in the XELOX arm and 43% in the FOLFOX4 arm. The median time to progression was 16 weeks in both arms.The median overall survival was 21 weeks with XELOX and 25 weeks with FOLFOX4. CONCLUSIONS: Oxaliplatin-based combination therapy showed moderate clinical activity with acceptable toxicity in patients who had progressive disease after receiving gemcitabine-based chemotherapy for advanced and/or metastatic pancreatic cancer. We conclude that XELOX is similar in terms of efficacy and toxicity profile to FOLFOX4 in the sec-ond-line treatment of metastatic pancreatic cancer.

Studies concerning adjuvant systemic therapy and prognosis in male breast carcinoma (MBC) are limited. We aimed to evaluate outcome of the changing practices of adjuvant systemic treatment and survival in operable MBC patients over the last two decades. The medical records of 148 MBC patients followed between the years 1986 and 2009 at 7 cancer center were evaluated retrospectively. One hundred and eighteen operable non-metastatic patients had sufficient data were included the study. One hundred and eighteen operable MBC were found to be eligible. Median age was 60 (range 29-83) years. Thirty-two percent of the patients had T3-4 tumors. Half of the patients had axillary lymph node-positive disease. The proportion of positivity of estrogen receptor(ER), progesterone receptor (PgR), and HER2 status were 82.9, 75.8, and 23.4%, respectively. Only, 7 patients had triple negative (TN). Adjuvant hormonotherapy was advised for 76.8% whereas adjuvant chemotherapy for 73.7% of the patients. Median follow-up was 40.9 months (range 3.8-186 months). Locoregional and/or distant recurrence developed in thirty-eight patients (32.2%). Twenty-three patients died during the follow-up period. Five-year disease-free survival (DFS) was found to be 60%, whereas overall survival (OS) was 82%. Larger tumor size and lymph node positivity were statistically significant poor prognostic factors for OS. Although statistical insignificant, patients with HER2-positive tumors have worse DFS (52 vs. 120 months, log rank P = .73) and OS (85 vs. 144 months, log rank P = .30) than HER2-negative ones. Although the frequency of the use of adjuvant systemic therapy in MBC has been increasing and survival rates improving for the last decades, lymph node status and tumor size are still the most important determining factors for prognosis. There is a need for further prognostic information in men with HER2-positive or TN breast cancer.

Chronic lymphocytic leukemia (CLL) is the most common type of leukemia worldwide. It is an indolent disease, almost exclusively of B-cell origin. Some CLLs evolve into a more aggressive lymphoid malignancy. The most common of these is Richter's syndrome. Transformation to acute lymphoblastic leukemia, plasma cell leukemia, multiple myeloma, or Hodgkin's disease (HD) may also occur. CLL patients are also at a significantly increased risk of developing a second malignant neoplasm later in life. One of the most common of these is HD. Herein, we report a case of HD in an elderly man with a history of B-cell CLL.

Juniper tar (cade oil) is distilled from the branches and wood of Juniperus oxycedrus. It contains etheric oils, triterpene and phenols, and is used for many purposes in folk medicine. A case is reported of a previously healthy man who ingested a spoonful of home-made extract of Juniperus oxycedrus. The poisoning caused fever, severe hypotension, renal failure, hepatotoxicity, and severe cutaneous burns on the face. After supportive and symptomatic treatment, the patient improved and was discharged in a good condition on the eleventh day.

The olive has a history almost as long as that of Western civilization and has been looked upon as a sign of hope, peace, and sacredness. Olive oil, extracted from the olive, is the principal source of dietary fat in the Mediterranean basin. The composition differs from that of other dietary fats in that olive oil is rich in monounsaturated fatty acids. Even other than as a source of monounsaturated fats, olive oil has own unique effects. Accumulating evidence suggests that olive oil may have beneficial health effects, especially when it comes to reducing risk factors for coronary heart diseases, preventing cancer, and modifying immune and inflammatory responses. However, evidence remains limited, definitive conclusions are difficult to draw, and there remains a significant need for further studies, particularly prospective cohort and well-designed, controlled intervention studies. In this manuscript, the beneficial health effects of olive oil are reviewed, with particular attention paid to cancer prevention and immune functions..
