Preoperative platelet-to-lymphocyte ratio is a predictor of prognosis in patients with ampullary carcinoma.

AIM: To emphasize the significance of the platelet-to-lymphocyte ratio (PLR) in estimating the postoperative prognosis or survival measures in patients with carcinoma of the ampulla of Vater. METHODS: We retrospectively reviewed 82 patients, who underwent pancreaticoduodenectomy for ampullary carcinoma between July 2001 and April 2014. We investigated the predictive significance of the preoperative PLR for disease-free survival (DFS) or overall survival (OS). The possible correlations between the PLR and clinical or pathological features were also evaluated. RESULTS: The 5-year DFS and OS rates of the patients with carcinoma of the ampulla of Vater after pancreaticoduodenectomy were 51 % and 64 %, respectively. Multivariate analysis revealed a significantly worse OS in patients with a PLR ≥ 212 [hazard ratio (HR): 3.446; 95% confidence interval (CI): 1.4-8.43; p = 0.007], lymphovascular invasion (HR: 2.973; 95% CI: 1.25-7.03; p = 0.013), or pathological stage pT3/4 (HR: 2.761; 95% CI: 1-7.1; p = 0.035). Similarly, DFS was significantly worse in patients with lymphovascular invasion (HR: 2.24; 95% CI: 1.1-4.56; p = 0.025) or stage pT3/4 (HR: 2.243; 95% CI, 1.03-4.84; p = 0.04). CONCLUSION: The preoperative PLR shows a predictive significance for the prognosis of postoperative patients with carcinoma of the ampulla of Vater. We suggest that because of its predictive value, the PLR can be used in the development of further approaches to monitor and manage patients with poor prognosis Tab. 4, Fig. 1, Ref. 45).

Accessory spleen hypertrophy mimicking colon cancer metastasis.

Accessory spleen is a congenital form of an ectopic splenic tissue. In this report, we present a case of a patient who was followed with the diagnosis of rectal and sigmoid colon cancer and an accessory spleen hypertrophy, which was thought to be colon cancer metastasis in the left hypochondriac region. After colectomy and splenectomy, accessory spleen that mimics cancer metastasis was diffrentially diagnosed using scintigraphy.

Unusual metastases of lung cancer: bulbus oculi and maxillary sinus.

Lung adenocarcinoma often makes metastasis to the brain, liver, kidneys, bone, bone marrow and adrenal glands. It can also make metastasis to other parts of the body rarely for example eye, nose, parotid gland and paranasal sinus. We did not encounter with combined ocular bulbus and the maxillary sinus metastases of lung cancer in the accessible literature. In this case report, a patient who was combined ocular bulbus and the maxillary sinus metastases of lung adenocarcinoma will be discussed.

Capecitabine/cisplatin doublet in anthracycline and taxane pretreated and HER-2 negative metastatic breast carcinoma patients.

PURPOSE: To evaluate the activity and toxicity of the combination of capecitabine and cisplatin (CapCisp) in anthracycline- and taxane-pretreated HER-2 negative metastatic breast carcinoma (MBC) female patients. METHODS: Patients with HER-2 negative MBC pretreated with anthracycline and taxane and who were then treated with CapCisp combination were retrospectively evaluated. All patients received Cap 1000 mg/m(2) on days 1-14, and Cisp 60 mg/m(2) on day 1, repeated every 3 weeks. In case of disease control without severe toxicity, single agent Cap was continued until progression or unacceptable toxicities after Cisp cessation. RESULTS: Sixty-four MBC patients with median age 43 years (range 20-66) were included the study. Infiltrative ductal carcinoma prevailed (85.9%). Ten percent of the patients had grade I, 42% grade II, and 48.0% grade III tumors. Estrogen receptor (ER) and progesterone receptor (PR) were positive in 48.4 and 51.6% of the patients, respectively. Twenty-eight percent of the patients had triple negative tumors. Almost the entire patient group had this regimen as a third-line treatment. The median combination chemotherapy cycles were 6 (range 2-8). Twenty-seven non-progressive patients continued treatment with single-agent Cap. Median single-agent Cap cycles after the combination chemotherapy were 4 (range 1-38). Disease control rate was 81.3% (complete response 6.3%; partial response 48.4%, stable disease 26.6%, progressive disease 18.8%). Median follow-up time was 10.6 months. Median time to disease progression was 7 months, median overall survival (OS) was 17 months (95% CI, 6.9-16.1) measured from the start of CapCisp chemotherapy. There were no treatment-related deaths. The most frequent grade 3-4 toxicities were neutropenia (8.1%), nausea - vomiting (7.8%) and thrombocytopenia (6.3%). CONCLUSION: CapCisp doublet has an encouraging antitumor activity with acceptable and manageable toxicity in anthracycline- and taxane-pretreated HER-2 negative metastatic breast carcinoma patients.

Comparative efficacy study of 5-year letrozole or anastrozole in postmenopausal hormone receptor-positive early breast cancer.

PURPOSE: To compare the efficacy of adjuvant anastrozole and letrozole in hormone receptor-positive postmenopausal patients with early breast cancer. METHODS: A total of 569 hormone receptor-positive postmenopausal early breast cancer patients were included and analyzed in this study. Of them 238 were taking adjuvant anastrozole and 331 adjuvant letrozole. Demographic and medical data including age, menopausal status, weight, height, treatment history and comorbid diseases were collected from their medical charts. RESULTS: In both anastrozole and letrozole users, the baseline clinicopathologic characteristics and the treatment history with radiotherapy and chemotherapy were similar. The median patient follow-up was 26.4 months. In the anastrozole arm disease free survival (DFS) was 94.9, 81.3 and 66.0%, whereas in the letrozole arm DFS was 90.6, 78.7 and 68.5% in the first, third and fifth years, respectively (p=0.25). Median overall survival (OS) could not be reached due to the low number of events in both arms. Three-year survival rate in the anastrozole arm was 98.8%, whereas in the letrozole arm it was 96.7% (p = 0.20). CONCLUSION: This study showed that both letrozole and anastrozole have similar effects on DFS and OS in the adjuvant hormonal treatment of postmenopausal hormone receptor-positive breast cancer. We believe that this retrospective study is the first to directly compare the efficacy of letrozole and anastrozole.

Duration of anti-HER2 blockage therapy may improve survival in HER2 positive metastatic breast carcinoma patients.

PURPOSE: The duration of anti-HER2 blockage therapy in metastatic breast cancer patients is still unclear. We aimed to evaluate the effect of the anti-HER2 blockage therapy duration and other factors on survival in HER2 positive metastatic breast carcinoma (MBC) patients. METHODS: The medical records of 193 HER2 positive MBC patients, who did not have the opportunity to receive adjuvant trastuzumab therapy but had received trastuzumab in the metastatic setting were retrospectively evaluated. RESULTS: The median age at diagnosis was 45.0 years (range 21-83). Ninety-two (47.7%) patients received palliative trastuzumab < 6 months median, whereas 101 patients received trastuzumab ≥ 6 months median. The median number of trastuzumab cycles was 8 (range 1-51). Median survival after breast cancer recurrence was 31.0 months (range 24.3-37.7). The duration of trastuzumab therapy had a significant impact on the prognosis of recurrent breast cancer (22.0 vs 49.0 months, for ≤ 6 months of treatment duration, respectively; p<0.0001). Survival after breast cancer recurrence for the patients who received lapatinib plus capecitabine vs those who did not was significantly different (59 patients, p=0.005). Moreover, there was a statistically significant relationship between prolonged lapatinib plus capecitabine combination therapy and improved survival after disease recurrence (p=0.022). In the multivariate Cox regression analysis, treatment with trastuzumab > 6 months (p=0.003) was the only independent prognostic factor for survival after breast cancer recurrence. CONCLUSION: The duration of anti-HER2 blockage therapies, especially with trastuzumab, seems to improve survival of HER2-positive metastatic breast cancer patients who were not previously treated with adjuvant trastuzumab, regardless of other therapies.

Variations in tumor marker levels in metastatic breast cancer patients according to tumor subtypes.

PURPOSE: To investigate whether serum CA 15-3 and CEA levels show differences among subgroups of breast cancer patients at the time of diagnosis of early-stage disease and at disease relapse. METHODS: Patients with metastatic breast cancer diagnosed from 2000 to 2010 were retrospectively analyzed. Data were obtained from medical charts. CA 15-3 and CEA levels of patients with metastatic disease at the time of diagnosis or who relapsed during follow-up were evaluated. Four different breast cancer subtypes were defined: estrogen receptor (ER) and/or progesterone receptor (PR) positive and HER-2 negative (luminal A), ER and/or PR positive and HER-2 positive (luminal B), ER and PR negative and HER-2 positive (HER-2 overexpressing) and triple negative (ER, PR and HER-2 negative). Fifty-eight (13.7%) of the patients were metastatic at the time of diagnosis. RESULTS: 423 metastatic breast cancer patients were included. Of the patients, 232 (54.8%) had luminal A disease, 70 (16.5%) luminal B, 53 (12.5%) HER-2 overexpressing, and 68 (16.1%) triple negative disease. Preoperative CA 15-3 levels were raised in 48.1% of the luminal A group, in 42.8% of the luminal B group, in 26.0% of the HER-2 overexpressing group, and in 33.3% of the triple negative group. CA 15-3 levels after relapse were raised in 44.5% of the luminal A group, in 33.3% of the luminal B, in 28.9% of the HER-2 overexpressing, and in 38.8% of the triple negative group. Preoperative CEA levels were elevated in 44.3% of the luminal A group, in 28.5% of the luminal B, in 43.4% of the HER-2 overexpressing, and in 14.3% of the triple negative group. CEA levels after relapse were raised in 60.8%, 54.7%, 51.1%, and 36.0% of the patients in the 4 subgroups, respectively. CONCLUSION: This study showed that there are differences between the breast cancer subgroups in terms of tumor marker levels in metastatic breast cancer patients. Tumor marker elevation was lower in the triple negative group as compared to the luminal groups. Monitoring CEA levels in luminal A group may be beneficial in determining early relapses. However, this retrospective study requires further prospective confirmative cohort studies.

Breast cancer in octogenarian women: clinical characteristics and outcome.

PURPOSE: Breast cancer incidence increases in the elderly but data on treatment and outcomes of elderly patients is limited. We assessed the clinicopathological features and outcomes of our patients with breast cancer aged ≥80 years in comparison with their younger postmenopausal counterparts. METHODS: The records of 83 patients diagnosed with breast cancer after the age of 80 (group 1) between 2003 and 2011 in 4 different centers were retrospectively evaluated and the clinicopathological features and outcomes were assessed in comparison with a control group (group 2) of 249 patients aged between 60-70 years. RESULTS: Median ages at diagnosis were 82 years (range 80-95) and 64 years (range 60-70) for group 1 and group 2, respectively. The incidence of invasive cancers other than ductal or lobular type was higher in group 1 than in group 2 (20 vs 8%; p=0.0177rpar;. More patients in group 1 had Charlson Comorbidty scores ≥1 than those in group 2 (49 vs 36%; p=0.011). Patients in group 1 had more conservative operations and less axillary node dissections (ALND) and they received chemotherapy, trastuzumab or radiotherapy less frequently compared to their younger counterparts in group 2. Median follow up period was 36 months (range 1-178) in group 1 and 24 months (range 12-217) in group 2. Five-year disease free survival (DFS) was 53.7 and 75.9) (p=0.005), 5-year overall survival (OS) was 61.9% and 80.47percnt; in group 1 and group 2 (p=0.001), respectively. Advanced stage (stage IV vs stage I, II, III, p=0.051) and cerbB2 positivity (p<0.001) were found to be associated with shorter DFS in patients ≥80 years of age. CONCLUSION: Although the majority of patients were undertreated in our study according to the current guidelines, mortality rates were quite low. Different biology of the disease in the elderly might explain this difference.

Administration of contrast media just before cisplatin-based chemotherapy increases cisplatin-induced nephrotoxicity.

PURPOSE: There is a clinical need to predict the probability of cisplatin-induced nephrotoxicity (CIN) in order to make decisions about patient management and relevant preventive measures. The purpose of this study was to develop a risk prediction methodology of CIN. METHODS: 197 consecutive cancer patients, whose serum creatinine was measured at least 48 h before every cycle of cisplatin-based chemotherapy, were included in the study. Demographic and clinical data were collected from the patient medical records. Renal function was evaluated at least 48 h before treatment (day 0) of each cycle, based on the Modification of Diet in Renal Disease (MDRD) formula. CIN was defined as a decrease of ≥ 25% in glomerular filtration rate (GFR) compared to baseline GFR values. RESULTS: The mean age of the study population was 54.5±9.6 years. Fifty-eight patients (29.4%) whose GFR had decreased by at least 25% compared to baseline values formed the CIN group, and the remaining 139 patients formed the non-CIN group. No significant differences were noted between the CIN and non-CIN groups in terms of age, gender, body mass index and smoking history. Metastatic disease was similar in both groups (p=0.86). History of hypertension (p=0.81), diabetes mellitus (p=0.72), and cardiovascular disease (p=0.58) were similar in the two groups. Chemotherapeutic agents used concurrently with cisplatin were similar in both groups. Significantly more radiologic examinations using contrast media were performed in the CIN group compared with the non-CIN group (p=0.01). In patients exposed to contrast media within a week before cisplatin administration, the risk of CIN was 2.56-fold higher (957 percent; CI 1.28-5.11) than in patients without such exposure (p=0.009). CONCLUSION: In patients with exposure to contrast media within a week before cisplatin administration, the risk of CIN was significantly higher than in patients without such an exposure. No additional risk factors for CIN were found in this retrospective observational study.

Evaluation of the renal function using cystatin C level in the patients receiving cisplatin-based chemotherapy.

OBJECTIVE: There are some data regarding the role of cystatin C, a cysteine proteinase inhibitor, in determining the glomerular filtration rate (GFR) more accurately. We aimed to evaluate the correlation of serum cystatin C levels with the serum creatinine levels and GFR calculated by Cockcroft-Gault and modification of diet in renal disease (MDRD) formulations in the patients who received cisplatin-based chemotherapy. We also intended to demonstrate its potential use in the early prediction of the renal function changes in these patients. MATERIALS AND METHODS: In the study, 34 patients receiving cisplatin-based chemotherapy with various malignancies were included. The levels of cisplatin were determined prior to the chemotherapy and at the end of cisplatin infusion during the therapy. GFR was calculated by Cockcroft-Gault and MDRD formulations prior to the therapy and at the end of the third course. RESULTS: A statistically significant linear correlation was found between the serum levels of cystatin C and creatinine prior to the chemotherapy (r = 0.42, p = 0.013). However, there was no correlation among the level of cystatin C subsequent to the cisplatin infusion and serum creatinine level following the third course and MDRD and creatinine clearance-Cockcroft-Gault formulations. CONCLUSION: Even though the serum cystatin C levels were correlated with the serum creatinine levels in our study, it was concluded that it was not an appropriate parameter to predict the potential impairments in the renal function during the chemotherapy.

A rare coincidence: facioscapulohumeral muscular dystrophy and breast cancer.

AIM: Facioscapulohumeral muscular dystrophy (FSHD) is an autosomally inherited neuromuscular disorder and may be associated with increased cancer risk. PATIENT: A 69-year old female admitted to hospital with complaint of left axillary mass who had diagnosis of FSHD in her adulthood period. RESULTS: Bilateral breast cancer diagnosis was made and the patient underwent bilateral mastectomy. Following the operation, adjuvant chemotherapy and radiotherapy performed and hormonal therapy started. CONCLUSION: The patients with congenital muscular dystrophy might have an increased risk of malignancy. We consider that some genetic alterations in FSHD might have contributed to the development of bilateral breast cancer in our patient.

Efficacy of adjuvant aromatase inhibitor in hormone receptor-positive postmenopausal breast cancer patients according to the body mass index.

BACKGROUND: Increased adiposity may trigger signalling pathways that induce aromatase expression. As aromatase inhibitors exert their effects by blocking the aromatase enzyme, higher body mass index (BMI) can reduce the effect of aromatase inhibitors. Thus, we aimed to investigate retrospectively the effect of BMI on the efficacy of aromatase inhibitors in hormone receptor-positive postmenopausal patients with breast cancer. METHODS: Newly diagnosed hormone receptor-positive breast cancer patients who were postmenopausal and non-metastatic were enrolled to the study. Patients with BMI ranging between 18.5 and 24.9 kgm(-2) were considered as normal weight patients (Arm A, n=102), and patients with a BMI ranging ≥ 25 kgm(-2) were grouped as overweight and obese patients (Arm B, n=399). RESULTS: In both normal weight and overweight patients, the baseline clinico-pathologic properties and the treatment history with radiotherapy and chemotherapy were similar, and with no statistically significant difference. In normal weight patients disease-free survival (DFS) rate was 93.7% and 77.6%, whereas in overweight and obese patients DFS rate was 96.8% and 85.5% in the first and third years, respectively, (P=0.08). Three year survival rate in Arm A patients was 98.3%, whereas in Arm B was 98.0% (P=0.57). When anastrozole was compared with letrozole in the subgroup analysis no difference with regard to DFS and overall survival was detected. CONCLUSION: These results, contradictory to the prior results, show that BMI has no worse effect on outcomes of aromatase inhibitors in postmenopausal hormone receptor-positive breast cancer patients. In the subgroup analysis, letrozole and anastrozole had similar survival outcomes.

Taxanes in the adjuvant treatment of node-negative breast cancer patients.

PURPOSE: Although the use of regimens with adjuvant taxanes is a standard approach in node-positive breast cancer, the use of taxanes in node-negative breast cancer is still controversial. In this search, we aimed to evaluate the data about the use of taxanes in high-risk node-negative patients. METHODS: Studies were retrieved by searching the Pubmed database. Randomized phase III studies on the use of regimens with adjuvant taxanes in early-stage breast cancer were screened and, among them, the studies that included node-negative patients were included in the evaluation. RESULTS: Data on the adjuvant use of taxanes in nodenegative patients were classified into 3 categories: a) studies that evaluated both node-positive and node-negative patients; b) meta-analyses on the use of adjuvant taxanes; and c) studies that included node-negative patients alone. The results of the studies that evaluated both node-positive and node-negative patients and the meta-analyses were evaluated according to the node-negative subgroup analyses. While two of these studies did not show difference in disease-free survival (DFS) for the node-negative subgroup, one study showed a difference in DFS. The only data for the adjuvant use of taxanes in only node-negative breast cancers belong to GEICAM 9805 study and, according to its results, docetaxel provided a difference in DFS in high-risk node-negative patients. CONCLUSION: Data about the adjuvant use of taxanes in node-negative patients are limited compared to the studies in which both node-positive and node-negative subgroups are evaluated. In the light of these studies, it is impossible to make a comment about the use of taxanes in node-negative patients. However, GEICAM 9805 study has shown positive results on DFS in high-risk node-negative breast cancer patients with adjuvant taxanes.

Multiple primary malignant neoplasms: multi-center results from Turkey.

PURPOSE: Multiple primary malignant neoplasms (MPMNs) are defined as a diagnosis of two or more indepen-dent primary malignancies of different histologies/origins in an individual. The frequency of MPMN is being increasing. In this study we aimed to determine the frequency and clinical features of second primary cancers (SPCs). METHODS: From January 1990 to December 2010, patients with MPMNs were screened in 5 centers. Data were obtained retrospectively from hospital charts. RESULTS: Three hundred seventy-seven patients with MPMNs were evaluated. The median age at initial cancer diagnosis was 61 years (range 18-88). The median age at second cancer was 64 years (range 20-89). The median time between two cancer diagnoses was 15 months (range 0-504). Male to female ratio was 1.44 (M/F 223/154). The most frequent initial cancer types were head and neck (54 patients, 14.3%), breast (54 patients, 14.3%), and colorectal (43 patients, 11.4%). The most frequent second cancer types were lung (76 patients, 20.2%), colorectal (39 patients, 10.3%) and breast (33 patients, 8.8%). The most common cancer pairs in females were breast-gynecologic cancers (15 patients, 9.7%), colorectal-breast cancers (9 patients, 5.8%) and breast-colorectal cancers (7 patients, 4.5%). The most common cancer pairs in males were head and neck-lung cancers (29 patients, 13%), bladder-lung cancers (9 patients, 4%), and bladder-prostate cancers (7 patients, 3%). The median follow up was 36 months (range 17horbar;595). CONCLUSION: Physicians should be aware of SPCs probabilities. Newly developed suspicious lesions should be evaluated rigorously. Histopathologic evaluations of suspicious lesions for second tumors should be used extensively if needed. In our series, the most common pairs were breast-gynecologic cancers in females and head and neck-lung cancers in males.
