ABSTRACT

Histiocytic sarcoma (HS) is an extremely rare and aggressive hematopoietic tumor. Although it can be seen at any anatomic location, the most common primary sites are skin as extranodal region, locations including the lymph nodes and gastrointestinal tract. To the best of our knowledge, in light of PubMed search, this is the first primary tonsillar HS case presented with disseminated metastases at the time of diagnosis. A 58-year-old male patient applied with swelling on the right side of the neck, difficulty in swallowing, and weight loss. Positron emission tomography computed tomography was performed and increased pathological 18F fluorodeoxy D glucose uptake was detected in the right palatine tonsil, bilateral cervical multiple lymph nodes, liver masses, intra abdominal lymph nodes, and nodular lesion in the left adrenal gland. Tonsillectomy was performed and the pathological result was reported as HS. The patient did not respond to any treatment and had died after 5 months from the date of diagnosis. In conclusion, HS is generally diagnosed at advanced stage, it has limited chemotherapy response and high mortality rates. To understand this rare disease's pathophysiological and clinical features, further investigations are needed.

ABSTRACT

Tamoxifen plays a critical role in the treatment of hormone receptor-positive breast cancer. Despite these great benefits against breast cancer, tamoxifen increases the risk of endometrial pathologies such as endometrial hyperplasia, polyp, and neoplasms because of agonistic effect on endometrial tissues. Therefore, gynecologic follow-up should be carried out during tamoxifen treatment. Uterine tumors are frequently detected as the result of presentation with abnormal uterine bleeding. In addition, genital tract's metastases from distant primary tumors can present with abnormal uterine bleeding. Therefore, it is important to determine whether the uterine mass is metastatic or primary because different treatment modalities are used for them. In this context, breast carcinomas are the most frequent metastatic tumors, particularly invasive lobular carcinoma. Here, we report an invasive lobular carcinoma case that presented with abnormal uterine bleeding while receiving tamoxifen therapy and has metastasize in the uterus.

ABSTRACT

Membraneous nephropathy (MN) is the most commonly occurring nephrotic syndrome in adults as well as the most common paraneoplastic nephropathy associated with solid tumors, and it is mostly associated with gastrointestinal system and lung carcinomas. Accurate diagnosis is important as the treatment of paraneoplastic glomerulonephritis is very varied from that of idiopathic ones. In the current report, a case of a patient that was referred with proteinuria and edema and was diagnosed with lung cancer, and responded markedly to treatment of malignancy, with improvement of MN, is presented. Active cancer is present in all patients with paraneoplastic MN. In numerous patients, the paraneoplastic MN and cancer diagnoses are made within one year of each other. The treatment of paraneoplastic syndromes is usually associated with the treatment of primary malignancy. There are conflicting data on which treatment modality is more suitable. In conclusion, further studies are required in order to determine the actual incidence of cancer in patients with nephropathy, explain the physiopathological association between cancer and nephropathy and to determine the most suitable treatment approaches.

ABSTRACT

BACKGROUND: Small bowel adenocarcinoma (SBA) is a rare tumor of the gastrointestinal system with poor prognosis. Because these are rarely encountered tumors, the aim of this multicenter study was evaluation of prognostic factors and adjuvant chemotherapy in patients with curatively resected SBA. MATERIALS AND METHODS: A total of 78 patients diagnosed with curatively resected SBA were involved in the retrospective study. Forty-eight patients received 1 of 3 different chemotherapy regimens, whereas 30 patients did not receive any adjuvant treatment. No adjuvant and adjuvant chemotherapy cohorts were matched (1:1) by propensity scores based on the likelihood of receiving chemotherapy or the survival hazard from Cox modeling. Overall survival (OS) was compared with Kaplan-Meier estimates. RESULTS: Median age of 78 patients with curatively resected SBA was 58, and 59% of these were men. According to TNM classification, 8 (10%) of the patients were at stage I, 26 (34%) were at stage II, and 44 (56%) were at stage III. Median follow-up duration was 29 months. Three-year median disease-free survival (DFS) and OS were 62.5% and 67.0%, respectively. In univariate analysis, presence of vascular invasion, perineural invasion, lymph node involvement, and presence of positive surgical margin were significant predictors of poor survival. Multivariate analysis showed that the only adverse prognostic factor independently related with OS was the presence of positive surgical margin (hazard ratio, 0.37; 95% confidence interval, 0.11-1.26; P = .01). Neither DFS nor OS was found to be significantly improved by the adjuvant chemotherapy in both matched and unmatched cohorts. CONCLUSIONS: Only status of surgical margin was determined to be an independent prognostic factor in patients with SBA who underwent curative resection.

ABSTRACT

The objectives of this study were to compare progression-free survival (PFS) with somatostatin analog (SSA) versus chemotherapy (CTx) in first-line therapy and to determine the patient group in which these treatments were more effective in neuroendocrine tumors (NETs) with a Ki-67 index of 20% or less. Patients who received SSA or CTx and had unresectable locally advanced and metastatic NETs with a Ki-67 index of 20% or less were retrospectively selected from 13 centers in the Turkish database between 2000 and 2015. One hundred and sixty-five patients were enrolled. The median age was 56 years and the male-to-female ratio was 1.09. Seventy-four (45%) patients were of grade 1 NET and 91 (55%) were of grade 2. SSA was given to 104 patients, whereas 61 were treated with CTx. The objective response rate after SSA was 15.4%; another 73.1% had stable disease. The objective response rate after CTx was 36.1%, and 40.9% had stable disease (P=0.008). The median PFS in SSA patients was 21 months (95% confidence interval: 12.4-29.6), and 8 months for CTx (95% confidence interval: 5.5-10.6) (P<0.001). There was no significant difference between PFS of receiving SSA and CTx in pancreatic neuroendocrine tumor (PNET) patients; however, the PFS of receiving SSA was longer in non-PNET patients (P<0.001). SSA was better treatment in advanced NET patients with a Ki-67 index of less than 5%, having a primary resected and a performance status of 0 (P<0.05). SSA may be preferred over CTx in advanced NET patients with low-to-intermediate grade.

ABSTRACT

PURPOSE: Small bowel adenocarcinoma (SBA) is a rare tumor of the gastrointestinal system with poor prognosis. Since these are rarely encountered tumors, there are limited numbers of studies investigating systemic treatment in advanced SBA. The purpose of this study was to evaluate the prognostic factors and systemic treatments in patients with advance SBA. METHODS: Seventy-one patients from 18 Centers with advanced SBA were included in the study. Fifty-six patients received one of the four different chemotherapy regimens as first-line therapy and 15 patients were treated with best supportive care (BSC). RESULTS: Of the 71 patients, 42 (59%) were male and 29 (41%) female with a median age of 56 years. Median follow- up duration was 14.3 months. The median progression free survival (PFS) and overall survival (OS) were 7 and 13 months, respectively (N=71). In patients treated with FOLFOX (N=18), FOLFIRI (N=11), cisplatin-5-fluorouracil/ 5-FU (N=17) and gemcitabine alone (N=10), median PFS was 7, 8, 8 and 5 months, respectively, while median OS was 15, 16, 15 and 11 months, respectively. No significant differences between chemotherapy groups were noticed in terms of PFS and OS. Univariate analysis revealed that chemotherapy administration, de novo metastatic disease, ECOG PS 0 and 1, and overall response to therapy were significantly related to improved outcome. Only overall response to treatment was found to be significantly prognostic in multivariate analysis (p=0.001). CONCLUSIONS: In this study, overall response to chemotherapy emerged as the single significant prognostic factor for advanced SBAs. Platin and irinotecan based regimens achieved similar survival outcomes in advanced SBA patients.

ABSTRACT

PURPOSE: The aim of this study was to determine risk factors for brain metastasis as the first site of disease recurrence in patients with HER2-positive early-stage breast cancer (EBC) who received adjuvant trastuzumab. METHODS: Medical records of 588 female patients who received 52-week adjuvant trastuzumab from 14 centers were evaluated. Cumulative incidence functions for brain metastasis as the first site of disease recurrence and the effect of covariates on brain metastasis were evaluated in a competing risk analysis and competing risks regression, respectively. RESULTS: Median follow-up time was 36 months. Cumulative incidence of brain metastasis at 12 months and 24 months was 0.6% and 2%, respectively. HER2-enriched subtype (ER- and PR-) tumor (p = 0.001, RR: 3.4, 95% CI: 1.33-8.71) and stage 3 disease (p = 0.0032, RR: 9.39, 95% CI: 1.33-8.71) were significant risk factors for development of brain metastasis as the first site of recurrence. CONCLUSIONS: In patients with HER2 positive EBC who received adjuvant trastuzumab, HER2-enriched subtype (ER- and PR-) tumor and stage 3 disease were associated with increased risk of brain metastasis as the first site of disease recurrence.

ABSTRACT

Most data on prognostic factors for patients with high-grade undifferentiated pleomorphic sarcoma (HGUPS) is obtained from analyses of soft tissue sarcomas. The purpose of this study was to evaluate the clinicopathologic features and their impact on outcomes specifically in patients diagnosed with HGUPS. In this multicenter trial, we retrospectively analyzed 112 patients who were diagnosed and treated at 12 different institutions in Turkey. We collected data concerning the patients, tumor characteristics, and treatment modalities. There were 69 males (61.6 %) and 43 females (38.4 %). Median age was 56 years (19-90). The most common anatomic site of tumor origin was the upper extremity. Pleomorphic variant was the predominant histological subtype. Median tumor size was 8.2 cm (0.6-30 cm). Tumors were mainly deeply seated (57.1 %). Fifty-seven patients (50.9 %) were stage II and the remainder were stage III at the time of diagnosis. Median follow-up was 30 months (2-160). The primary site of distant metastasis was the lung (73.5 %) and the second most common site was the liver (11.7 %). The 5-year overall survival, distant metastasis-free survival, and local recurrence-free survival rates were 56.3, 53.4, and 67.2 %, respectively. Multivariate analysis showed that Eastern Cooperative Oncology Group (ECOG) performance score of II (p = 0.033), deep tumor location (p = 0.000), and development of distant metastasis (p = 0.004) were negatively correlated with overall survival, and perioperative radiotherapy and negative microscopic margins were significant factors for local control rates (p = 0.000 for each). Deep tumor location (p = 0.003) was the only adverse factor related to distant metastasis-free survival. Deep tumor location, ECOG performance score of II, and development of distant metastasis carry a poor prognostic implication on overall survival. These will aid clinicians in predicting survival and treatment decision.

ABSTRACT

AIM: We investigated the clinicopathological features in patients with recurrent RCC within 5 years or more than 5 years after nephrectomy and determined predictors of survival and response treatment after recurrence. MATERIALS AND METHODS: We retrospectively evaluated 144 patients with disease recurrence; 73 had recurrence more than 5 years after radical nephrectomy. We compared clinicopathological characteristics in patients with disease recurrence before vs. after 5 years. In addition, we investigated predictors of survival and response to treatment after recurrence. RESULTS: Seventy-one patients (49%) were diagnosed with recurrence within 5 years after radical nephrectomy (early recurrence) and 73 patients (51%) were diagnosed with recurrence more than 5 years after radical nephrectomy (late recurrence). Fuhrman grade, tumor necrosis and lymphovascular invasion were statistically significantly different between the two groups (p<0.001, p=0.013, p=0.026, respectively). The late recurrence patients were significantly associated with the Memorial Sloan Kettering Cancer Center (MSKCC) favorable risk group compared to patients with early recurrence (p=0.001). From the time of disease recurrence, median Overall Survival (OS) was 36.0 (95% Confidence Interval (CI) 30.7-41.2) months in the late recurrence group, and 19 (95% CI 15.4-22.5) months in the early recurrence group (p=0.01). The median Progression Free Survival (PFS) was 6 (95% CI 3.87-8.12) months in the early recurrence group, and 18 (95% CI 15.4-20.5) months for the late recurrence group (p<0.001). CONCLUSION: Early recurrence was significantly associated with Fuhrman grade 3-4, tumor necrosis, lymphovascular invasion, MSKCC poor-risk group compared to patients with late recurrence. The study also demonstrated a potential prognostic value of late recurrence in terms of PFS and OS.

ABSTRACT

BACKGROUND: There is no standard treatment for patients with colorectal cancer (CRC) progressing after irinotecan and oxaliplatin treatment. Here we aimed to retrospectively evaluate the efficacy and tolerability of raltitrexed in combination with oral 5-fluoropyrimidine (uracil tegafur-UFT) or mitomycin C as salvage therapy in mCRC patients. MATERIALS AND METHODS: A total of 62 patients who had received raltitrexed combined with UFT or mitomycin C were identified between December 2008 and June 2013. They were given raltitrexed 2.6 mg/m2 (max 5 mg) i.v. on day 1 in combination with either oral UFT 500 mg/day on days 1-14 every 3 weeks (group A) or mitomycin C 6 mg/m2 i.v. on day every 3 weeks (group B). RESULTS: Forty-two patients (67.7%) were in group A and 20 (32.2%) in group B. In 15 patients (24%) grade 3/4 toxicity was observed, resulting in dose reduction, and in 13 patients (20.9%) dose delay was necessary. The median progression free survival (PFS) was 3 months (95%CI 2.65-3.34) and median overall survival (OS) was 6 months (95%CI 2.09-9.90) in the whole group. Median PFS was 3 months (95%CI 2.60-3.39) in group A vs 3 months (95%CI 1.64-4.35) in group B (p=0.90). Median OS was 6 months (95%CI 2.47-9.53) in group A vs 12 months (95%CI 2.83-21.1) in group B (p=0.46). CONCLUSIONS: The combination of raltitrexed with UFT or mitomycin C seem to be a salvage therapy option due to safety profile and moderate clinical activity in heavily-pretreated mCRC patients.

ABSTRACT

Sorafenib is a multi-targeted tyrosine kinase receptor inhibitor used to treat patients with advanced gastrointestinal stromal tumors (GISTs). The present study evaluated the efficacy and tolerability of sorafenib therapy for patients with GISTs. Between January 2001 and November 2012, 25 patients, from multiple centers, who had received sorafenib as the third- or fourth-line treatment for GISTs were investigated retrospectively. In total, 17 patients were male and eight were female. The median age was 54.0 years (range, 16-82 years). From the patients, 21 received imatinib for longer than six months and four received it for less than six months. The clinical benefit rate of sorafenib was 40.0%. Treatment-related adverse events were reported in 72% of patients. These adverse events were generally mild to moderate in intensity. The median progression-free survival (PFS) and overall survival (OS) times of the patients who received sorafenib were 7.2 and 15.2 months, respectively. The duration of imatinib usage was an independent prognostic factor for PFS and OS. Sorafenib is an effective treatment in patients with GISTs showing a clinical benefit rate of 40.0% and an acceptable tolerability.

ABSTRACT

BACKGROUND/AIMS: Sunitinib is a multi-targeted thyrosine kinase receptor inhibitor used in patients with advanced gastrointestinal stromal tumours (GISTs). We evaluated the efficacy and tolerability of sunitinib therapy in Turkish patients with GISTs. METHODOLOGY: Between January 2001 and April 2012, 57 patients who had progressive disease or experienced unacceptable toxicity during imatinib treatment from multiple centers were investigated retrospectively. RESULTS: Thirty-three patients were male and 24 were female. The median age was 55 years (range; 16-84 years). Thirty-eight of the patients received imatinib for longer than 12 months, 13 patients received for 6-12 months, and 6 patients received for less than six months. The clinical benefit of sunitinib was 73.7%. Treatment-related adverse events were reported in 78% of the patients. Adverse events were generally mild to moderate in intensity. The median progression free survival (PFS) and overall survival (OS) of the patients that received sunitinib were 10.8 months and 23.9 months, respectively. The time of imatinib usage and response to sunitinib were independent prognostic factors for PFS and OS. Also, tumor size was an independent prognostic factor for PFS. CONCLUSIONS: Sunitinib is an effective treatment in Turkish patients with GISTs, with a clinical benefit of 73.7% and shows an acceptable tolerability.

ABSTRACT

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.

ABSTRACT

PURPOSE: The efficacy and tolerability of bevacizumab every 2 or 4 weeks using the same dosage in combination with biweekly FOLFIRI were retrospectively evaluated in metastatic colorectal cancer (mCRC) patients in the first-line and second-line therapy. PATIENTS AND METHODS: A total of 332 patients from six centers were evaluated. The patients had received biweekly FOLFIRI in combination with bevacizumab 5 mg/kg every 2 weeks or every 4 weeks schedule for various reasons in individual patients. RESULTS: Approximately 70 % of all patients had 2-week treatment schedule. In the first-line therapy (n = 240), the overall response rate (ORR) was 34.1 % in 2-week and 36.3 % in 4-week groups. Median progression-free survival (PFS) was 8 months (95 %CI, 6.8-9.2) and 9 months (95 %CI, 6.6-11.4) (p = 0.074), and median overall survival (OS) was 22 months (95 %CI, 15.8-28.2) and 20 months (95 %CI, 8.1-31.9) (p = 0.612) in 2- and 4-week groups, respectively. One-year survival rate was 76.2 % for 2-week group and 73.2 % for 4-week group. In the second-line therapy (n = 92), the ORR was similar between the groups (24.5 vs 25.9 % in 2- and 4-week groups, respectively). Median PFS was 6 months (95 %CI, 4.7-7.3) and 11 months (95 %CI, 6.3-15.7) (p = 0.074), and median OS was 15 months (95 %CI, 9.6-20.4) and 17 months (95 %CI, 13.7-20.3) (p = 0.456) for 2-week and for 4-week groups, respectively. One-year survival rate was 61.3 % for 2-week and 71.3 % for 4-week groups. Toxicity profile was similar in 2- and 4-week groups and included neutropenia, febrile neutropenia, nausea and vomiting, diarrhea, mucositis, bleeding, hypertension, thromboembolism and fistulization. CONCLUSION: Bevacizumab 5 mg/kg every 2 weeks or every 4 weeks in combination with biweekly FOLFIRI had similar efficacy and tolerability in mCRC. Because of the retrospective nature of our study, the data should be examined cautiously. However, our study clearly points out the need for determination of optimum biological dosing interval of bevacizumab in well-designed, prospective, randomized trials.

ABSTRACT

Intravesical administration of Bacillus Calmette-Guérin is used as a treatment method in superficial bladder cancer. While it is generally well tolerated, serious side effects may develop. Granulomatous hepatitis cases have been previously reported; however, only one case with tuberculous peritonitis exists in the current literature. We hereby present two cases, one of which is the second tubercular peritonitis case following Bacillus Calmette-Guérin treatment to be reported, and the other a case with granulomatous hepatitis. Complete cure was achieved in both cases with specific therapy. In the patient who developed peritonitis, intravesical Bacillus Calmette-Guérin therapy was recommenced after antituberculosis treatment, and completed without further complications.

ABSTRACT

AIM: To evaluate endoscopic and histopathologic aspects of acute gastric injury due to ingestion of high-dose acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) with respect to some risk factors and patient characteristics. METHODS: The study group consists of 50 patients admitted to emergency department with high dose analgesic ingestion (group I) with suicidal intent. Thirty patients with or without mild complaints of dyspepsia (group II) were selected as the control group. The study group was stratified according to the use of type and number of analgesics. Endoscopic findings were evaluated according to the Lanza score (LS), expressing the severity of the gastroduodenal damage and biopsies according to a scoring system based on histopathologic findings of acute erosive gastritis. RESULTS: Gastroduodenal damage was signifi-cantly more severe in group I compared to group II (P < 0.01). The LS was similar in both groups Ia and Ib. However LS was significantly higher in patients who had ingested multiple NSAIDs (group Ic) compared to other patients (P < 0.01). The LS was correlated to age (P < 0.01) and total amount of drug ingested (P < 0.05) in group I; but it was not correlated with Helicobacter pylori (H pylori) infection or duration of exposure (P > 0.05). The biopsy score (BS) was higher in group I than group II (P < 0.01), and higher in group Ib than group Ia (P < 0.05). CONCLUSION: The histopathologic damage was more severe among NSAID ingesting patients compared to those ingesting only acetaminophen and there is no significant difference in the endoscopic findings between the groups. There is no significant difference in the LS between the groups. This lack of significance is remarkable in terms of the gastric effects of high-dose acetaminophen.

ABSTRACT

INTRODUCTION: Non-specific abnormalities in liver function tests might accompany the clinical course of hyperthyroidism. Hyperthyroidism can cause the elevation of hepatic enzymes and bilirubin. Jaundice is rare in overt hyperthyroidism, especially in subclinical hyperthyroidism. On the other hand, the use of anti-thyroid drugs has rarely been associated with toxic hepatitis and cholestatic jaundice. CASE PRESENTATION: Here we present two cases of cholestasis that accompanied two distinct forms of clinical hyperthyroidism. The first patient had a clinical presentation of severe cholestasis in the absence of congestive failure related to hyperthyroidism. The second case had developed intrahepatic cholestasis in the presence of subclinical hyperthyroidism, and improved with rifampicin treatment. CONCLUSION: Hyperthyroidism should be a consideration in non-specific liver dysfunction.
