Purpose: To compare the efficacy and adverse effect profiles of the first-line treatment of patients with KRAS wild type metastatic colorectal cancer (CRC) in Turkey who were treated based on regimens including bevacizumab, cetuximab and panitumumab., Methods: This retrospective multicenter observational study involved a total of 238 patients who received chemotherapy in combination with either bevacizumab or cetuximab or panitumumab as first-line therapy for KRAS wild-type metastatic colorectal cancer. Patients with full medical records having pathological diagnosis of CRC adenocarcinoma were included in the study. The demographic, laboratory, histopathological and clinical characteristics of the patients were determined, and three groups were compared based on the study variables., Results: The mean age of the entire sample (n=238) was 58±11 years, 64% of which were male. The most frequent tumor localization was the rectum (37%) and G2 was the most common tumor grade (59.7%). About 63% of the patients had metastatic disease at diagnosis, with the most common site of metastasis being lung (14.7%) and liver (52.5%). Overall survival (OS) was 63.9%, while 1-, 3- and 5-year survival rates were 91.7, 56.6 and 36.9%, respectively. The expected mean survival was 49.1 months (95% CI, 42.9-55.3). The 1-, 3- and 5-year progression-free survival (PFS) rates following first-line treatment were 65.3, 26.1 and 5.6%, respectively, while disease free survival (DFS) in patients without metastasis at diagnosis was 68.5%. An analysis carried out disregarding which treatment the patients received (FOLFOX or FOLFIRI) revealed that a panitumumab-containing combination resulted in poorer prognosis compared to bevacizumab or cetuximab-containing combination (p<0.001). With regard to the adverse effect profile, the most common adverse effects were neuropathy and neutropenia in patients receiving FOLFOX-bevacizumab; neutropenia and perforation in patients receiving FOLFIRI-bevacizumab; rash and pustular infection in patients receiving FOLFIRI-cetuximab; and diarrhea in patients who received FOLFIRI-panitumumab combination., Conclusion: This is the first multicenter study performed in Turkey evaluating the response to treatment and adverse effects in patients with KRAS wild-type metastatic colorectal cancer.

Purpose: Almost half of all patients diagnosed with non-small cell lung cancer (NSCLC) have distant metastases at presentation. One-third of patients with NSCLC will have brain metastases. Without effective treatment, the median survival is only 1 month. However, it is difficult to treat brain metastases with systemic chemotherapy since the agents have difficulty crossing the blood-brain barrier. Therefore, it is important to estimate the patient's survival prognosis. The aim of this study was to analyze prognostic factors for survival in Turkish patients who received chemotherapy after cranial irradiation for NSCLC with brain metastases., Methods: We retrospectively reviewed 698 patients with brain metastases resulting from NSCLC. Ten potential prognostic variables were chosen for analysis. Univariate and multivariate analyses were conducted to identify prognostic factors associated with overall survival (OS)., Results: Among the 10 variables for univariate analysis, six were identified to have prognostic significance; these included sex, smoking history, histology, number of brain metastases, extracranial metastases, and neurosurgical resection. Multivariate analysis by the Cox proportional hazard model showed that a smoking history, extracranial metastases, and neurosurgical resection were independent negative prognostic factors for OS., Conclusion: Smoking history, extracranial metastases, and neurosurgical resection were considered independent negative prognostic factors for OS. These findings may facilitate pretreatment prediction of survival and can be used for selecting patients for more appropriate treatment options., Competing Interests: There are no conflicts of interest

Purpose: The purpose of this study was to analyse the association between the 18F-2-deoxy-2-fluorodeoxyglucose maximum standardized uptake value (SUVmax) of metastatic sites and molecular subtypes and survival in metastatic breast cancer (MBC) patients., Methods: Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) was performed in 176 MBC patients before any therapeutic intervention. The FDG uptakes of metastatic sites were evaluated using the SUVmax. Histopathological prognostic parameters, such as the tumor size, grade, lymph node involvement, lymphovascular invasion, estrogen (ER), progesterone receptors (PR), HER2 status and Ki67 were determined from the primary breast tumor tissue. The SUVmax of the metastatic sites was assessed in relation to the molecular subtypes and survival in univariate and multivariate analyses. Cox regression analysis was used to evaluate the associations between SUVmax measurements and overall survival (OS)., Results: The mean SUVmax of 176 tumors was 8.0. Among the subtypes 49 (28.8%) were luminal A, 51 (28.9%) luminal B, 35 (19.8%) HER2-overexpressing, and 41 (23.2%) triple- negative, and the corresponding means of SUVmax were 5.6, 7.4, 11.4, 11.0, respectively. A cut-off value of ≤8.4 yielded 80% sensitivity and 57.1% specificity with an area under the receiver operating characteristics curve (AUC) of 0.731 for predicting that a tumor was of the luminal A subtype. A cut-off value of SUVmax ≥10.05 yielded 62.9% sensitivity and 67.4% specificity with an AUC of 0.648 for predicting a HER2 overexpressing subtype. A cut-off value of SUVmax ≥9.25 yielded 61% sensitivity and 64.4% specificity with an AUC of 0.660 for predicting a triple-negative subtype. The SUVmax could not effectively differentiate patients with luminal B subtype. Cox regression analysis showed that in patients with MBC, a SUVmax ≤7.55 acted as an independent negative prognostic factor for OS (hazard ratio/HR = 1.552)., Conclusion: The SUVmax of metastatic sites on pretreatment 18F-FDG PET/CT may be an independent prognostic factor for the diagnosis of molecular phenotypes and survival in MBC patients.

Purpose: To determine the predictive value of the mean platelet volume (MPV) and the MPV/platelet count ratio on the development of isolated bone metastasis in patients with breast cancer., Methods: A total of 121 previously untreated female patients with isolated bone metastases from breast cancer (group 1) were included in this retrospective cohort study. The patients enrolled in this study had similar age, biological subtypes, and duration of follow-up after diagnosis. Group 1 was compared with both 71 previously untreated women with breast cancer with no metastases at all (group 2) and 39 healthy women (group 3). Demographic data, laboratory tests and histological features of all of the patients in groups 1 and 2 were recorded and the study variables from each of the three groups were compared., Results: In group 1, the cut-off value (9.2 fL) for the MPV was determined and patients were stratified into 4 subgroups. The MPV was higher in group 1 than in either group 2 or group 3. Group 1 patients had a MPV of 8.8±3.1 fL (mean 5.1, range: 6.1-15.6) and the cut-off value for MPV was 9.2 fl. For patients in group 1, the MPV distribution was stratified into 4 groups as follows: group A included MPV values <6.08 fL, in group B values ranged from 6.09 to 8.46 fL, group C included values from 8.47 to 10.05 fL, and group D included patients with MPV values >10.06 fL. MPV and the presence of lymphovascular invasion were found to be independent risk factors for the development of isolated bone metastases., Conclusion: We concluded that MPV can be used to predict the development of isolated bone metastases.

St. John's Wort (SJW) is an old herb which has long been consumed widely for its anti-inflammatory, antiviral, and anti-depressive properties. Here we present a detailed clinical evaluation of three cases (two colon and one duodenal adenocarcinoma) with remarkable and intensive lymphoplasmocytic host reaction, at the basal part of tumor, intensive fibrosis, giant cells, plasma cell increase in lymph nodes and few giant cells in germinal centers in resection specimens. The observation of similar host reaction in those tumors having otherwise usual appearance was interesting. None of the cases received neoadjuvant chemoradiotherapy or additional treatment before surgery but only SJW. These cases are presented to increase the awareness about such cases. Further research is needed to reveal the possible effect of SJW, which has long been consumed for different treatment purposes, on human tumors.

Purpose: Currently, there are several oxaliplatin combination regimens for first-line therapy of metastatic colorectal cancer (mCRC). In this study, we compared the survival outcomes of mCRC patients treated with bevacizumab in combination with either modified 5-FU/FA/oxaliplatin (mFOL- FOX6) or capecitabine/oxaliplatin (XELOX)., Methods: We designed a two-arm retrospective study of mCRC patients with adenocarcinoma of the colon or rectum who were treated with bevacizumab and either mFOLFOX6 or XELOX and who had complete clinical and treatment data. We analysed their therapeutic responses, adverse events, progression-free survival (PFS), and overall survival (OS), and then determined whether there were any statistically significant differences., Results: A total of 131 patients (85 male; 65% and 46 female; 35%) were evaluated. Fifty-seven patients (43.5%) were treated with bevacizumab and mFOLFOX6 and 74 (56.5%) with bevacizumab and XELOX. The median PFS was 9.1 months (95% CI, 4.9-13.1) and 10 months (95% CI, 4.2-15.9) in the mFOLFOX6 and XELOX arms, respectively (p=0.610). The median OS was 29 months (95% CI, 21.6- 34.3) and 27.5 months (95% CI 20-38) in the mFOLFOX6 and XELOX arms (p=0.812), respectively. The most common reason for treatment withdrawal was disease progression (102 patients; 91%) and the most common grade 3-4 toxicity was neuropathy (≤14%)., Conclusion: Our results show that XELOX is a safe and effective alternative to mFOLFOX6 when combined with bevacizumab as first-line treatment for mCRC patients.

Teratomas are rarely seen in adults, and presacral region is an area where they rarely settle in. Similarly, only about 1% of teratomas show malignant transformation. Malignant transformation is often associated with the area where teratoma settles in. Malignant transformation of mediastinal teratomas is more frequent than the ones located in retroperitoneal area and gonad. They most commonly show rhabdomyosarcoma, primitive neuroectodermal tumor, enteric adenocarcinoma, and leukemia transformation. In teratomas showing malignant transformation, the clinical course is aggressive; and survival of patients with metastatic disease is very low. The primary treatment of teratomas with malignant transformations is surgical. Effect of radiotherapy and chemotherapy is not clear in patients, to whom surgical operation cannot be applied, or those who are with residual tumor, even if surgical operation can be applied to them, or those who are at metastatic stage. In this paper, we presented a 76-year-old male patient due to the histologic diagnosis of mucinous adenocarcinoma within teratoma, in whom approximately 7 cm presacral mass was found during the radiographic examination made by the reason of low back pain and pelvic pain.

Background: Several prognostic factors have been studied in NSCLC, although it is unknown which is most useful. In this study, we aimed to investigate whether pre-treatment serum albumin level has prognostic value in patients with Stage IIIB NSCLC., Materials and Methods: This cross-sectional study included a total of 204 patients with Stage IIIB NSCLC who met the inclusion criteria. Pre-treatment serum albumin levels and demographic, clinical, and histological characteristics, as well as laboratory variables were recorded. A cut-off value was defined for serum albumin level and the patients were stratified into four groups on thios basis., Results: The majority of the patients was males and smokers, with a history of weight loss, and squamous histological type of lung cancer. The mean serum albumin level was 3.2±1.7 g/dL (range, 2.11-4.36 g/dL). A cut-off value 3.11 g/dL was set and among the patients with a lower level, 68% had adenocarcinoma and 82% were smokers. The patients with low serum albumin levels had a lower response rate to e first-line chemotherapy with a shorter progression-free survival and overall survival. Multivariate analysis showed that low serum albumin level was an independent poor prognostic factor for NSCLC., Conclusions: This study results suggest that low serum albumin level is an independent poor prognostic factor in patients with Stage IIIB NSCLC, associated with reduction in the response rate to first-line therapy and survival rates.

Aim of the Study: Our aim was to determine the activity and toxicity of uracil/tegafur and leucovorin combination in metastatic colorectal cancer (mCRC) patients who have progressed with all currently active agents., Material and Methods: This study was a retrospective analysis of 50 mCRC patients who had previously failed to respond to all available chemotherapeutics and who received subsequent treatment with uracil/tegafur 250 mg/m(2) d1-5 in combination with leucovorin 90 mg/day, d1-5 followed by two days' rest., Results: The median age of the patients was 60 years. Most of them (60%) were male. Bevacizumab was used in 65% and cetuximab in 55% of the patients. Thirty-nine patients (78%) were treated with uracil/tegafur in the fourth line setting. The median treatment duration was 4.2 months (range, 2-24 months). The objective response rate and the disease control rate were 4% and 34%, respectively. Median progression-free survival was 4.1 months (95% CI, 3.6-4.6 months) and overall survival was 6.6 months (95% CI, 4.5-8.6 months). Grade 3 or 4 toxicity was seen in 20% (n = 10) of the patients while 60% (n = 6) of them required dose reductions., Conclusions: This retrospective data show that uracil/tegafur may be considered in heavily pretreated mCRC patients because of its activity, lower toxicity, and feasibility.

Leiomyosarcoma is a rare form of cancer commonly found in the retroperitoneum, uterus, stomach, small intestine and vascular tissue. Surgery with a wide margin of resection is the most effective treatment. Nevertheless, metastasis is common and generally occurs within the first 3 years. The liver and lungs are the most common sites of metastasis in leiomyosarcoma. Other sites of metastasis include bone, spleen, soft tissues and brain. Metastatic tumours of the clitoris are extremely rare. As cited in the literature, the most common cancers that metastasize to the clitoris are breast, bladder, renal and gastric. Here, we report a case of a clitoral mass in a 64-year-old woman who received an operation for retroperitoneal leiomyosarcoma 4 years prior. Mass resection was performed. The pathological diagnosis was a leiomyosarcoma metastasis. The patient also presented with brain and lung metastases at the time of the clitoral metastasis. This is the first case of clitoral and brain metastases originating from a retroperitoneal leiomyosarcoma.

Purpose: We aimed to evaluate the effects of hormone receptor, HER2, and epidermal growth factor receptor (EGFR) expression on epithelial ovarian cancer (EOC) prognosis and investigate whether or not phenotypic subtypes might exist., Materials and Methods: The medical records of 82 patients who were diagnosed with EOC between 2003 and 2012 and treated by platinum-based chemotherapy were retrospectively evaluated. Expression of EGFR, oestrogen (ER), progesterone (PR), and cerbB2 (HER2) receptors were assessed immunohistochemically on paraffin-embedded tissues of these patients. Three phenotypic subtypes were defined according to ER, PR, and HER2 expression and associations of these with EGFR expression, clinicopathologic features, platinum sensitivity, and survival were investigated., Results: When we classified EOC patients into three subtypes, 63.4% had hormone receptor positive (HR(+)) (considering breast cancer subtypes, luminal A), 18.3% had triple negative, and 18.3% had HER2(+) disease. EGFR positivity was observed in 37 patients (45.1%) and was significantly more frequent with advanced disease (p=0.013). However, no significant association with other clinicopathologic features and platinum sensitivity was observed. HER2(+) patients had significantly poorer outcomes than HER2(-) counterparts (triple negative and HR positive patients) (p=0.019). Multivariate analysis demonstrated that the strongest risk factor for death was residual disease after primary surgery., Conclusions: Triple negative EOC may not be an aggressive phenotype as in breast cancer. The HER2 positive EOC has more aggressive behaviour compared to triple negative and HR(+) phenotypes. EGFR expression is more frequent in advanced tumours, but is not related with poorer outcome. Additional ovarian cancer molecular subtyping using gene expression analysis may provide more reliable data.

Background: The purpose of this study was to analyze our series of liver resections for metastatic colorectal carcinoma (mCRC) to determine prognostic factors affecting survival and to evaluate the potential roles of neoadjuvant or adjuvant chemotherapy., Materials and Methods: Ninety-nine patients who underwent metastasectomy for liver metastases due to colorectal cancer at the Department of Medical Oncology, 9 Eylul University Hospital between 1996 and 2010 were evaluated in this study. The patients were followed through July 2013. Demographic, perioperative, laboratory, radiological and chemotherapy as well as survival data were obtained by retrospective chart review., Results: In 47 (47.5%) patients, liver metastases were unresectable at initial evaluation; the remaining 52 (52.5%) patients exhibited resectable liver metastases. Simultaneous hepatic resection was applied to 52 (35.4%) patients with synchronous metastasis, whereas 5 (64.5%) patients underwent hepatic resection after neoadjuvant chemotherapy. Forty-two patients with metachronous metastasis underwent hepatic resection following neoadjuvant chemotherapy. R0 resection was obtained in 79 (79.8%) patients. A second hepatectomy was performed in 22 (23.2%) patients. Adjuvant chemotherapy was given to 85 (85.9%) patients after metastasectomy. The median disease-free and overall survivals after initial metastasectomy were 12 and 37 months, respectively, the 1-year, 3-year and 5-year disease-free survival (DFS) and overall survival (OS) rates being 46.5%, 24.3% and 17.9%and 92.3%, 59.0% and 39.0%, respectively. On multivariate analysis, the primary tumor site, tumor differentiation, resection margin and DFS were independent factors predicting better overall survival., Conclusions: In selected cases, hepatic metastasectomy for mCRC to the liver can result in long-term survival. Neoadjuvant chemotherapy did not exert a positive effect on DFS or OS. Adjuvant chemotherapy also did not appear to impact DFS and OS.

Background: The role of second-line therapy in metastatic pancreatic cancer is not clear. In this study, we aimed to explore the second-line efficiency of capecitabine and oxaliplatin (XELOX) in patients with advanced pancreatic cancer who have received gemcitabine-based first-line therapy., Materials and Methods: We retrospectively evaluated 47 patients with locally advanced or metastatic pancreatic cancer previously treated with gemcitabine-based first-line regimens. Treatment consisted of oxaliplatin 130 mg/m2 and capecitabine 1000 mg/m2 twice daily with a 3 week interval, until unacceptable toxicity or disease progression., Results: Median number of cycles was 4 (range, 2-10). The overall disease control rate was 38.3%. The median overall survival and progression-free survival from the start of second-line therapy were 23 weeks (95%CI: 16.6-29.5 weeks) and 12 weeks (95%CI: 9.8-14.4 weeks), respectively. The most common grade 3-4 toxicities were nausea, vomiting and hematologic side effects., Conclusions: Our result suggests that the combination of capecitabine and oxaliplatin was tolerated with manageable toxicity and showed encouraging activity as second-line treatment of advanced or metastatic pancreatic cancer patients with ECOG performance status 0-2.

Purpose: Erythrocyte mean corpuscular volume (MCV) increase has been described in patients treated with capecitabine. In this study, we sought to evaluate the potential association of the erythrocyte MCV increase with tumor response and survival in patients with metastatic colorectal cancer (mCRC) treated with capecitabine., Methods: A retrospective review of 131 patients with mCRC who were treated with capecitabine for at least 3 months at the Izmir Training and Research Hospital was undertaken. Complete blood count (CBC) including red blood cell indices were recorded at baseline and after 9 weeks from capecitabine treatment., Results: The mean patient age was 57.9 years (range 28- 82). In patients treated with capecitabine, MCV increased significantly at 9 weeks compared with baseline (p=0.000). Median ΔMCV [(post-treatment MCV values) - (baseline MCV values)] level was 9.3 fL. Patients were grouped according to ΔMCV into two groups (> 9.3 or ≥ 9.3) in order to carry out survival analysis and correlation with tumor response. ΔMCV was >9.3 in 65 patients and ≤9.3 in 66 patients. Fifty-six of the 65 patients with ΔMCV levels >9.3 and 37 of the 66 patients with ΔMCV levels ≤9.3 had a clinical benefit (complete response + partial response + stable disease) from capecitabine treatment (p=0.000). The difference between progression-free survival (PFS) and overall survival (OS) of the patients who had ΔMCV>9.3 and those who had ≤9.3 was statistically significant (9.48 and 6.94 months, p=0.001 respectively; and 17.5 and 13.6 months respectively, p=0.018). Univariate analysis suggested that a favorable prognosis for OS and PFS was associated with MCV increase (p=0.000). In multivariate analysis, MCV increase was independently associated with favorable survival outcomes., Conclusions: Erythrocyte MCV increase may be used as a predictive marker for treatment response, PFS and OS in patients with mCRC treated with capecitabine.

Chordomas are rare neoplasms arising from notochordal remnants and may develop anywhere in the body while the most common anatomic site is the sacrococcygeal area. The most effective treatment of chordoma is surgery. Chordomas rarely metastasize to lung, bone, soft tissue, liver, lymph nodes, and skin. However, there is currently no standard systemic treatment for advanced stage chordoma. Here, we reported a rare presentation of chordoma patient with liver only metastases and poor prognosis.

Purpose: The aim of this study was to investigate the effect of metabolic syndrome and insulin resistance at the time of diagnosis on the known prognostic factors of breast cancer in postmenopausal breast cancer patients., Methods: The study included 71 patients with a recent diagnosis of postmenopausal breast cancer, admitted at the Medical Oncology outpatient clinic of the Izmir Ataturk Training and Research Hospital between June 2010 and June 2011. We determined whether the patients had metabolic syndrome and insulin resistance at diagnosis, and recorded known prognostic factors, such as tumor size, axillary lymph node involvement, presence of distant metastasis, tumor grade, estrogen receptor (ER), progesterone receptor (PR), and CerbB-2 status., Results: Among 71 patients, 25 (35%) had metabolic syndrome at the time of diagnosis, and 33 (46%) had insulin resistance with Homeostasis Model of Assessment-Insulin Resistance (HOMA-IR)>2.7. No statistically significant difference was found in the prognostic values of breast cancer, i.e. tumor size, axillary lymph node involvement, distant metastasis, tumor grade, ER, PR, and CerbB-2 status between the patients with and without metabolic syndrome. There was no statistically significant difference in the prognostic factors of breast cancer at the time of diagnosis between 33 patients with insulin resistance and 38 patients without insulin resistance., Conclusion: Several previous studies showed a negative relationship between metabolic syndrome and insulin resistance and prognostic factors of breast cancer in postmenopausal breast cancer patients. However, our study failed to show such a relationship. The relationship between metabolic syndrome and insulin resistance and postmenopausal breast cancer was not well demonstrated due to the small number of patients, unknown duration of the metabolic syndrome and insulin resistance, and shorter follow-up period. Further studies are required to demonstrate the effect of metabolic syndrome and insulin resistance on the prognosis of breast cancer, including larger number of patients and longer follow-up periods.

Neuroendocrine carcinoma is a relatively rare tumor and its coexistence with other primary cancers is very exceptional. We present a case of a 63-year-old woman with biliary obstruction due to a high-grade neuroendocrine carcinoma located in ampulla of Vater who was found to have a synchronous sigmoid colon adenocarcinoma while undergoing staging laparotomy and pancreas head resection. Medical history was significant only for basal cell skin cancer. Immunohistochemical examination revealed the concurrence of histologically proved neuroendocrine carcinoma (chromogranin A, synaptophysin, and CD56 were positive) and Stage II (T3, N0, and M0) according to the TNM staging classification of colorectal cancer. The coexistence of neuroendocrine tumors with either synchronous or metachronous unrelated cancer is increasingly recognized. The patients with neuroendocrine carcinoma should be evaluated for secondary primary malignancies.

Purpose: Advanced pancreatic cancer (APC) has a poor prognosis and chemotherapy remains the primary treatment modality. Gemcitabine (GEM) and 5-fluorouracil (5-FU) are the most active drugs in the treatment of pancreatic cancer. This study evaluated the efficacy and tolerability of the combination of these agents in APC., Methods: Forty-four patients with APC were treated with GEM and infusional 5-FU with high dose leucovorin (LV5FU2) (GEMFUFOL regimen)., Results: A total of 240 chemotherapy cycles were administered. The overall response rate was 27.2%, and all responses were partial. Furthermore, disease stabilization was observed in 12 patients (27.2%). Median survival time and one-year survival rate were 9 months and 36.4%, respectively. The overall grade 3 or 4 adverse events were very low and mostly hematological., Conclusion: GEMFUFOL is still an active regimen for the treatment of APC and has an acceptable toxicity.

Somatostatin and its long-acting analogues are effective in symptom control in patients with functional neuroendocrine tumors; they are also able to control tumor growth. Somatostatin analogues are safe and generally well tolerated. In some cases they may cause serious complications. Somatostatin analogues are potent inhibitors of growth hormone (GH) and glucagon secretion. They cause impairment of hepatic glucose output and delay in intestinal absorption of carbohydrates. Patients with huge tumor mass and multiple liver metastases have increased risk of tumor-induced hypoglycemia. In these patients, long-acting octreotide may trigger serious hypoglycemia. The patients whose glucose control is dependent on counter-regulatory hormones should be monitored for the possibility of hypoglycemia. Herein, we present a patient with severe and prolonged hypoglycemia after long-acting octreotide treatment.

Background/aims: Gastric cancer in pregnancy is extremely rare and often diagnosed at advanced stages. Well-recognized pregnancy-related symptoms, such as nausea and epigastric discomfort, can be the first symptoms of gastric cancer. Thus, the diagnosis of gastric cancer in pregnancy is difficult. We herein report a case of gastric cancer in pregnancy to alert clinicians to this rare possibility., Materials and Methods: A 22-year- old nulliparous woman was examined by a gynecologist with a complaint of low abdominal pain. An abdominal ultrasound of the patient revealed 7th week of gestation and also showed massive ascites. She was referred to a hospital for further evaluation. Her other symptoms included loss of appetite, early satiety, and postprandial fullness. Gastroscopy demonstrated a tumor originating from the cardia and invading throughout the distal corpus. The histopathological diagnosis was gastric carcinoma with signet ring cells and her pregnancy was terminated. An explorative laparotomy revealed an unresectable gastric cancer and multiple peritoneal implants. Tumoral invasion was detected in pancreas and spleen. She was admitted to the medical oncology clinic and received a palliative chemotherapy. Bilateral double-J-stent placement was performed because of obstructive uropathy. A nasogastric tube was inserted for intestinal decompression, and total parenteral nutrition was administered. An adequate pain medication was given. To date (3 months after the diagnosis) the patient has been well without any signs of progression., Conclusion: Early diagnosis of gastric cancer is very important for a better outcome. The diagnosis may be delayed because mild gastrointestinal symptoms are common during pregnancy. Clinicians should take this into consideration in the differential diagnosis of persistent epigastric complaint during pregnancy. Suspicion and early upper gastrointestinal endoscopy are necessary.
