Panitumumab Associated Acute Pancreatitis.

INTRODUCTION: The addition of panitumumab to chemotherapy in wild-type metastatic colon cancer contributes to survival. While the skin related side effects of panitumumab are well known, we wanted to present a case where it was a possible cause of acute pancreatitis. CASE REPORT: The FOLFOX regimen was started in a 67-year-old patient with sigmoid colon cancer and multiple liver metastases. After 2 cycles, genetic tests were concluded and panitumumab 6 mg/kg was added to the treatment. The patient who presented with abdominal pain 2 days after the treatment was hospitalized with acute pancreaatitis. MANAGEMENT & OUTCOME: Abdominal tomography of the patient was compatible with acute pancreatitis. Oral intake was stopped, IV hydration was started. The patient, whose complaints regressed, was discharged on the 3rd day of hospitalization. DISCUSSION: Skin side effects related to panitumumab are observed quite frequently. Although panitumumab related gastrointestinal side effects have been reported, there is no data on acute pancreatitis. Panitumumab was added to the chemotherapy regimen he received, and it was thought that panitumumab might be the etiological factor in the case who developed pancreatitis.

Male Breast Cancer: Clinical, Demographical, and Pathological Features in a Cohort of 41 Patients.

Background and objective Male breast cancer (MBC) is a rare malignancy, and it accounts for less than 1% of all cancers in men. The pathogenesis of MBC remains unclear, with most available data obtained from single-center studies and retrospective series. The aim of this study was to share our experiences of MBC cases and to describe the characteristics of MBC patients. Materials and methods We retrospectively reviewed the records of 41 MBC cases and recorded the pathological, clinical, and demographic features of the patients. Data on progression-free survival (PFS) and overall survival (OS) were also recorded. Results The mean age of the patients was 64.1 ± 10.0 years. The most common histopathological subtype was invasive ductal carcinoma. Hormone receptor positivity was detected in 39 (95.1%) patients. Human epidermal growth factor receptor 2 (HER2) positivity was present in five (12.2%) patients. Most of the patients had early-stage disease. Surgery was the treatment of choice for most primary tumors. Thirty-nine (95.1%) patients received hormonotherapy, and 21 (51.2%) received systemic chemotherapy. OS was found to be 126.4 months and PFS was 83.2 months. The OS and PFS time in patients with a Nottingham Prognostic Index (NPI) score of <5.4 were longer than those with an NPI score of >5.4. Conclusion The hormone receptor status of most of the MBC patients was positive, and their HER2 status was negative. A multimodality approach was associated with longer survival, which has been reported in female patients with breast cancer as well. The NPI score is a useful tool for predicting survival time in MBC patients.

Steatohepatitis due to FOLFIRINOX regimen in adjuvant pancreas cancer treatment mimicking liver metastasis.

INTRODUCTION: The combination of fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) is more toxic than gemcitabine, but it is a safe regimen with manageable toxicities. CASE REPORT: We report a case with steatohepatitis mimicking liver metastasis as toxicity that was not seen in study patient population.Management and outcome: In the adjuvant statement with FOLFIRINOX due to biopsy, we give the same regimen by excluding metastasis. DISCUSSION: The adverse events of drugs are important predictive factor for treatment management, as important as efficacy. Especially the new lesion and metastasis is the most important factor for changing treatment. The clinicians must be careful about adverse events of regimens. CONCLUSION: FOLFIRINOX regimen is the most important combination in pancreas cancer adjuvant setting. This case shows us the different presentation of usual adverse event.

Sweet syndrome in a patient with chronic lymphocytic leukemia/small lymphocytic lymphoma: curious lymphocyte/neutrophil fluctuations.

UNLABELLED: Sweet syndrome, also referred to as acute febrile neutrophilic dermatosis, is characterized by tender, red inflammatory nodules or papules that occur in association with infection, malignancy, connective tissue disease, or following exposure to certain drugs. Here, we present Sweet syndrome in a case with small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL) which is a relatively rare co-occurrence. CONFLICT OF INTEREST: None declared.

Non-Hodgkin's lymphoma in a chronic myelocytic leukemia patient treated with imatinib.

Imatinib is an important example of tyrosine kinase inhibitors (TKIs) used in clinical practice. Imatinib blocks the ATP binding site of the Bcr-Abl fusion protein and selectively inhibits Bcr-Abl tyrosine kinase (TK) activity. Treatment of chronic myelocytic leukemia (CML) with imatinib is encouraging and it has an acceptable toxicity profile, and as such has changed the management of CML during the last decade. As with all drugs used in clinical practice, side effects of imatinib have been reported in studies with extended follow-up periods. In addition, some neoplastic disorders have been reported to occur during imatinib therapy. Herein we present a CML case that developed non-Hodgkin's lymphoma (NHL) while receiving imatinib treatment.
