BACKGROUNDIn the current study, the authors describe the M. D. Anderson experience with adjuvant systemic therapy in male breast carcinoma patients.METHODSA total of 156 men with a diagnosis of breast carcinoma registered and were treated at the M. D. Anderson Cancer Center between 1944 and 2001. One hundred thirty‐five men had nonmetastatic breast carcinoma at diagnosis and were included in this analysis. Patients' charts were retrospectively reviewed to obtain details of patient characteristics, adjuvant therapy, and outcomes. Analysis was performed with descriptive statistics; the log rank test was used to compare outcomes.RESULTSThe median patient age was 59 years (range, 25–80 yrs). Median follow‐up was 13.8 years (range, 0.6–32.5 yrs). Sixty percent of patients had tumors 2 cm or smaller. Pathologic lymph node involvement was seen in 55% of patients. Tumors were estrogen receptor‐positive in 85% of cases and progesterone receptor‐positive in 71%. Chemotherapy was administered to 32 men (84% with adjuvant chemotherapy, 6% with neoadjuvant chemotherapy, and 9% with both). Approximately 81% received anthracycline‐based regimens; 9% received additional taxanes; and 16% were treated with cyclophosphamide, methotrexate, and 5‐fluorouracil (CMF). The median number of cycles was 6 (range, 4–14 cycles). Thirty‐eight men received adjuvant hormonal therapy (92% received tamoxifen and 8% were treated with other therapy). The 5‐year and 10‐year overall survival rates were 86% and 75%, respectively, for men with lymph node‐negative disease and 70% and 43%, respectively, for men with lymph node‐positive disease. For men with lymph node‐positive disease, adjuvant chemotherapy was associated with a lower risk of death (hazards ratio [HR] of 0.78), although this difference was not statistically significant. Overall survival was significantly better for men who received adjuvant hormonal therapy (HR of 0.45; P = 0.01).CONCLUSIONSThis relatively large series of men with breast carcinoma suggests that men benefit from adjuvant systemic therapy for breast carcinoma, with the greatest benefit from adjuvant hormonal therapy.

Identifying elderly patients who will benefit from combination chemotherapy for pancreatic cancer remains a significant clinical challenge. An assessment of medical comorbidities and functional status plays a key role in determining fitness for intensive chemotherapeutic regimens in this important subset of patients.
Thrombotic microangiopathy is an uncommon but reported adverse effect of a variety of antineoplastic drugs, including chemotherapy agents such as mitomycin C and gemcitabine, and newer targeted agents such as the vascular endothelial growth factor inhibitors. We present a review of thrombotic microangiopathy associated with antineoplastic agents and its implications in current cancer therapy.
Tumor lysis syndrome (TLS) is a life-threatening condition which consists of a constellation of electrolyte imbalances, acute renal failure, seizure, and arrhythmias. It is most commonly seen with hematologic malignancies after the initiation of chemotherapy. However, it can also occur spontaneously, prior to treatment with cytotoxic agents. TLS has been rarely described with non-hematologic solid tumors, and it is even more uncommon to have spontaneous tumor lysis syndrome (STLS) in solid tumors. To our knowledge, only two cases of STLS in small-cell lung cancer (SCLC) were reported in the literature. Herein, we present the case of a patient with metastatic SCLC who developed STLS. Our case highlights that in the setting of metastatic solid tumors, STLS must be in the differential diagnosis, to allow prompt initiation of prophylaxis and treatment.
Essential thrombocythemia (ET) is a myeloproliferative neoplasm characterized by a clonal expansion of megakaryocytes. ET can result in both arterial and venous thrombosis. Involvement of the coronary arteries has been reported. Patients who harbor a CALR mutation are half as likely to suffer a thrombotic event as compared to patients with a JAK2 mutation. We report a case of CALR-mutated ET whose initial disease manifestation was a non-ST segment elevation myocardial infarction.
Primary bronchus-associated lymphoid tissue (BALT) lymphoma comprises 5% of non-Hodgkin’s lymphoma (NHL) and usually has an indolent course. Synchronous primary lung cancers with BALT lymphoma are seldom seen in patients with adenocarcinoma of the lung. Synchronous squamous cell carcinoma (SCC) and BALT lymphoma is an extremely rare occurrence. We report an unusual case of stage 4 BALT lymphoma requiring treatment that revealed an underlying ipsilateral mass causing a diagnostic dilemma. An 84-year-old female with a history of systemic lupus erythematosus, deep vein thrombosis, and thrombotic microangiopathy presented to the hospital with cough and dyspnea on exertion. A chest X-ray revealed right hemi-thorax opacification and computed tomography (CT) of the chest showed a large right effusion and a soft tissue density extending into the proximal right bronchus. She required repeated thoracentesis until the pleural fluid analysis showed the presence of small lymphocytes and bronchial washings revealed an abnormal B cell population consistent with extranodal marginal zone lymphoma. The patient received four cycles of bendamustine and rituximab resulting in near-complete resolution of the effusion. Four months from diagnosis, imaging showed an increase in the size of the soft tissue density with pathologic fluorodeoxyglucose (FDG) uptake on positron emission tomography (PET). A CT-guided biopsy was consistent with squamous cell lung cancer (SCLC) and radiotherapy was started for clinical stage 2 disease since the patient was not a surgical candidate. BALT lymphoma is a low-grade malignancy classified as extranodal marginal zone lymphoma with a five-year survival rate of over 80%. Several cases of synchronous lung adenocarcinoma and BALT lymphoma have been described. However, our case is among the rare few cases of synchronous occurrence of SCLC with BALT lymphoma. This report highlights the challenges associated with establishing an accurate and timely diagnosis.
Patient: Female, 53Final Diagnosis: Endometrial stromal sarcomaSymptoms: Abdominal distensionMedication: —Clinical Procedure: —Specialty: OncologyObjective:Rare co-existance of disease or pathologyBackground:Paraneoplastic hypercalcemia is a well-described complication associated with a variety of malignancies. However, its incidence in gynecological malignancies is low.Case Report:A 53-year-old woman presented with progressive abdominal distention and irregular vaginal bleeding of several weeks’ duration. A contrast CT abdomen and pelvis was significant for a mass in the lower uterine/cervical region, multiple peritoneal and omental masses, enlarged pelvic and paraaortic lymph nodes, and large-volume ascites. A pelvic exam revealed a fungating vaginal mass, with biopsy showing a high-grade tumor with immunohistochemical staining positive for vimentin, CD10, and cyclin D1, consistent with endometrial stromal sarcoma. During her hospitalization, the patient became increasingly lethargic. Workup showed severe hypercalcemia and evidence of acute kidney injury. The patient did not have evidence of bony metastatic disease on imaging studies. Further laboratory evaluation revealed an elevated PTHrP of 301 pg/mL (nl 14–27), a depressed PTH level of 3 pg/mL (nl 15–65), and a depressed 25-OH vitamin D level of 16 ng/mL (nl 30–100), consistent with humoral hypercalcemia of malignancy. The patient was treated with pamidronate, calcitonin, and intravenous fluids. She eventually required temporary hemodialysis and denosumab for refractory hypercalcemia, which improved her electrolyte abnormalities and clinical status.Conclusions:Uterine malignancies of various histologies are increasingly recognized as a cause of humoral hypercalcemia. They are an important differential diagnosis in a woman with hypercalcemia and abnormal vaginal bleeding or abdominal symptoms.
Systemic mastocytosis (SM) is a disease characterized by a clonal infiltration of mast cells affecting various tissues of the body. It is grouped into six different subtypes according to the World Health Organization classification. It is called indolent systemic mastocytosis (ISM) when there is no evidence of end organ dysfunction, while the presence of end organ dysfunction defines aggressive systemic mastocytosis (ASM). When SM coexists with a clonal hematological disorder, it is classified as systemic mastocytosis with associated clonal hematological nonmast cell lineage disease (SM-AHNMD). Over 80% of SM-AHNMD cases involve disorders of the myeloid cell lines. To our knowledge, there are only 8 reported cases to date of SM associated with a plasma cell disorder. We report a patient with ISM who was found to have concomitant smoldering multiple myeloma. His disease later progressed to ASM. We discuss this rare association between SM and a plasma cell disorder, and potential common pathophysiologic mechanisms linking the two disorders will be reviewed. We also discuss prognostic factors in SM as well as the management options considered during the evolution of the patient's disease.
