Acute Myeloid Leukemia in a Patient with Ovarian Carcinoma
The occurrence of myelodysplastic syndrome or acute myeloid leukemia has been reported after treatment with cytotoxic alkylating agent-based chemotherapy for solid tumors. We report a 50-year-old woman presented with abdominal distension, vomiting, and fatique. The abdominal tomography showed bilaterally ovarian masses and ascite. Surgery was performed and histopathology of the ovarian mass revealed moderately differentiated papillary adenocarcinoma of ovarian. The patient was treated with chemotherapy combination including paclitaxel and carboplatin for six cycles. At 4 years after chemotherapy, recurrence of the primary disease developed. She received carboplatin and paclitaxel. Two years later, complete blood count showed leukocyte count 15.700 /mm3 (15% myeloblasts), hemoglobin 8.7 g/dL, and platelet count 88.000 /mm3. Bone marrow examination and flow cytometry analysis were consistent with acute myeloid leukemia. Standard induction chemotherapy with idarubicin and cytosine arabinoside was administered with failure to achieve complete remission. At the follow-up, the patient died due to prolonged febrile neutropenia. In conclusion, patients who were treated with high dose or long term alkylating agents should particularly follow-up for secondary tumors
First-line treatment of patients with HER2-positive metastatic gastric and gastroesophageal junction cancer
Fluoropyrimidine+cisplatin/oxaliplatin+trastuzumab therapy is recommended for the first-line treatment of HER2-positive metastatic gastric adenocarcinoma. However, there is no comprehensive study on which platinum-based treatment should be preferred. This study aimed to compare the treatment response and survival characteristics of patients with HER2-positive metastatic gastric or gastroesophageal junction (GEJ) cancer who received fluorouracil, oxaliplatin, and leucovorin (mFOLFOX)+trastuzumab or cisplatin and fluorouracil (CF)+trastuzumab as first-line therapy. It was a multicenter, retrospective study of the Turkish Oncology Group, which included 243 patients from 21 oncology centers. There were 113 patients in the mFOLFOX+trastuzumab arm and 130 patients in the CF+trastuzumab arm. The median age was 62 years in the mFOLFOX+trastuzumab arm and 61 years in the CF+trastuzumab arm (P = 0.495). 81.4% of patients in the mFOLFOX+trastuzumab arm and 83.1% in the CF+trastuzumab arm had gastric tumor localization (P = 0.735). The median progression-free survival (PFS) was significantly higher in the mFOLFOX+trastuzumab arm (9.4 months vs. 7.3 months, P = 0.024). The median overall survival (OS) was similar in both groups (18.4 months vs. 15.1 months, P = 0.640). Maintenance trastuzumab was continued after chemotherapy in 101 patients. In this subgroup, the median OS was 23.3 months and the median PFS was 13.3 months. In conclusion, mFOLFOX+trastuzumab is similar to CF+trastuzumab in terms of the median OS, but it is more effective in terms of the median PFS in the first-line treatment of HER2-positive metastatic gastric and GEJ cancer. The choice of treatment should be made by considering the prominent toxicity findings of the chemotherapy regimens
P95 HER2 fragments and breast cancer outcome
HER2 is a 185-kDa transmembrane oncoprotein encoded by the HER2 gene. It is located on chromosome 17q21 and is overexpressed in approximately 15% of invasive breast cancers. In addition, it is a poor prognostic factor for survival and disease progression. Approximately 30% of HER2-positive tumors also express a series of carboxy-terminal HER2 fragments known as p95HER2, in addition to the full-length HER receptor. Previous studies have found that p95HER2 represents an independent prognostic marker in patients with HER2-positive disease. Moreover, p95HER2 status might be a decisive factor when choosing between different therapies because p95HER2 fragment-positive tumors are resistant to trastuzumab but respond to tyrosine kinase inhibitors, such as lapatinib, as do p95HER2-negative tumors. p95HER2 fragments arise through at least two different mechanisms: proteolytic shedding of the full-length p185HER2 receptor extracellular domain and translation of HER2 mRNA from internal initiation codons. The present review is based primarily on recent studies suggesting p95HER2 constitutes a new surrogate marker for an aggressive HER2-positive breast cancer subtype with distinct clinical and biological features
A decision-analytic model for early stage breast cancer: Lumpectomy vs mastectomy
The purpose was to construct a decision model that incorporated patient preferences over differing health state prospects and to analyze the decision context of early stage breast cancer patients in relation to two main surgical treatment options
A Case Of Multifocal Skin Metastases From Lung Cancer Presenting With Vasculitic-Type Cutaneous Nodule
Although cutaneous metastasis occurs usually at the terminal stage of the disease, it may be rarely concurrent with the diagnosis and may also present as the first sign of the illness. A 55-year-old male patient presented with vasculitic-type cutaneous nodular lesions and a necrotic distal phalangeal lesion developed over the last month. He was a tradesman and smoked 40 packets year. On physical examination, he was found to have multiple cutaneous lesions on the skin of the face, limbs, neck, scalp, dorsal side, fingers, subungual side, right leg, and feet. A skin lesion punch biopsy was performed and squamous cell carcinoma metastasis was detected. He was diagnosed as having squamous cell lung cancer with bronchoscopic biopsy. Although it is very rare, cutaneous metastases that is concurrent with the diagnosis of lung cancer may be the first sign of the disease. In patients with suspicious skin lesions, the patient's age, smoking history, and other symptoms should be evaluated and a biopsy should be performed.PubMe
