RESUMEN

Angiosarcoma (AS) is a rare and aggressive vascular neoplasm with very poor prognosis. Patients with extensive cutaneous AS who are not surgical candidates have very limited options since there is no standard treatment. Treatment options include radiation, chemotherapy, and angiogenesis inhibitor with varying success rates. Here, we report a case an 88 year old patient with extensive scalp angiosarcoma having biopsy proven remission with bevacizumab and radiotherapy without undergoing surgery.

RESUMEN

Hereditary cancer syndromes infer high cancer risks and require intensive surveillance. Identification of high-risk individuals among patients with colorectal cancer (CRC) needs improvement. METHODS: Three thousand three hundred ten unselected adults who underwent surgical resection for primary invasive CRC were prospectively accrued from 51 hospitals across Ohio between January 1, 2013, and December 31, 2016. Universal Tumor screening (UTS) for mismatch repair (MMR) deficiency was performed for all, and pathogenic germline variants (PGVs) were identified using multigene panel testing (MGPT) in those who met at least one inclusion criterion: MMR deficiency, diagnosed < 50 years, multiple primary tumors (CRC or endometrial cancer), or with a first-degree relative with CRC or endometrial cancer. RESULTS: Five hundred twenty-five patients (15.9%) had MMR deficiency. Two hundred thirty-four of 3,310 (7.1%; 16% of the 1,462 who received MGPT) had 248 PGVs in cancer susceptibility genes. One hundred forty-two (4.3%) had a PGV in an MMR gene, and 101 (3.1%) had a PGV in a non-MMR gene. Ten with Lynch syndrome (LS) also had a non-MMR PGV and were included in both groups. Two (0.06%) had constitutional MLH1 hypermethylation. Of unexplained MMR-deficient patients, 88.4% (76 of 86) had double somatic MMR mutations. Testing for only MMR genes in MMR-deficient patients would have missed 18 non-MMR gene PGVs (7.3% of total PGVs identified). Had UTS been the only method used to screen for hereditary cancer syndromes, 38.6% (91 of 236) would have been missed, including 6.3% (9 of 144) of those with LS. These results have treatment implications as 5.3% (175 of 3,310) had PGVs in genes with therapeutic targets. CONCLUSION: UTS alone is insufficient for identifying a large proportion of CRC patients with hereditary syndromes, including some with LS. At a minimum, 7.1% of individuals with CRC have a PGV and pan-cancer MGPT should be considered for all patients with CRC.

RESUMEN

BACKGROUND: Cerebral abscess is caused by inoculation of an organism into the brain parenchyma from a site distant from the central nervous system. Streptococcus intermedius (S. intermedius) is a commensal organism that is normally present in the aerodigestive tract and was reported to be the cause of brain abscesses after esophageal dilatation or upper endoscopy. CASE PRESENTATION: We report the case of a 53-year-old female who presented with hematemesis and melena followed by left-sided weakness. Initially, her hemiplegia was found to be secondary to a right thalamic brain abscess caused by S. intermedius. Investigations led to the diagnosis of a mid-esophageal squamous cell carcinoma. We hypothesize that the cause of the abscess with this bacterium that naturally resides in the digestive tract and oral cavity is secondary to hematogenous spread from breach in the mucosal integrity from ulceration due to the cancer. CONCLUSION: To our knowledge, our case is the first in the literature to describe a brain abscess caused by S. intermedius in association with a previously undiagnosed esophageal squamous cell carcinoma without any prior esophageal intervention.

RESUMEN

Bevacizumab is a humanized monoclonal antibody approved by the US Food and Drug Administration for use in combination with fluorouracil (FU)-based chemotherapy for first-line treatment of patients with metastatic colorectal carcinoma (CRC). Its mechanism of action is inhibition of tumor angiogenesis by neutralizing vascular endothelial growth factor. Adverse events resulting from its use include gastrointestinal perforation, wound-healing complications, hemorrhage, and arterial thromboembolism. We present a case of a 67-year-old man who developed Fournier's gangrene during treatment with bevacizumab 4 months after completing mFOLFOX6 (5-FU/leucovorin/oxaliplatin) for CRC. Other than bevacizumab, the patient had no medications and had no medical conditions that would predispose to Fournier's gangrene.
