Tumor Board Papers
- Somatic PTEN alterations are common in endometrial carcinoma (EC), but in rare cases PTEN mutations are associated with inherited syndromes. Here, we present a case of Cowden syndrome-associated EC. We discuss clinical, pathologic and molecular features of her tumor and PTEN-mutated EC, inherited syndromes predisposing to EC and PTEN-targeted therapies.
- A 73-year-old woman with metastatic vaginal mucosal melanoma that had progressed on ipilimumab and nivolumab experienced clinical and radiographic complete response to dual checkpoint inhibitor immunotherapy given in combination with high-dose plus low-dose radiation. General characteristics and treatment options in this disease are highlighted.
- A 36-year-old transgender man (assigned female at birth) on exogenous testosterone therapy was found to have stage IIA ovarian endometrioid carcinoma, and underwent adjuvant chemotherapy. Diffuse androgen receptor expression in the tumor initiated a multidisciplinary discussion regarding the safety of continuing exogenous testosterone as gender-affirming hormone therapy.
- SCCOHT is an aggressive malignancy linked to alterations of SMARCA4. We describe the diagnosis and therapy of a 32 year old who received multi-agent chemotherapy and underwent a second look operation with HIPEC followed by high-dose chemotherapy with stem cell transplant. Supportive care, oncofertility, and genetic counseling are described.
- Immature teratomas (IT) are rare and recurrences uncommon. A 12-year-old female with grade 3 (high-grade) ovarian IT underwent surgical resection but experienced early recurrences; the first was treated with surgery but the second was metastatic and managed with chemotherapy, resulting in growing-teratoma-syndrome and need for further surgery. She now remains well in uneventful clinical follow-up. We believe chemotherapy could be reserved for very carefully selected recurrent IT cases, which may alter the natural history of disease.
- Polymerase-epsilon (POLE)-mutated carcinomas are a rare, but well-known subtype of endometrial cancer. While typically associated with good prognosis, recurrences are documented. Here we present a case of recurrent POLE-mutated endometrial cancer, discuss pathologic features, current methods of molecular classification, and explore therapeutic implications for the POLE-mutation phenotype.
- A case of stage IB2 cervical cancer at 27 weeks of pregnancy, treated with neoadjuvant chemotherapy followed by radical Cesarean hysterectomy with full pelvic and infra-mesenteric lymphadenectomy, and adjuvant chemo-radiation is described. While she remains without disease, her baby was diagnosed with acute myelogenous leukemia. We highlight the pre-operative work-up, treatment options, safety, feasibility, and outcomes for the mother and her fetus.
- A 42-year-old woman with a germline BRCA2 mutation and recurrent low-grade endometrioid endometrial adenocarcinoma experienced clinical and radiographic response to the poly (ADP ribose) polymerase (PARP) inhibitor, olaparib. Molecular and treatment factors are discussed.
- A 32 year-old nulligravid woman with a uterine mass underwent exploratory laparotomy with myomectomy. Final pathology revealed a low-grade endometrial stromal sarcoma (ESS) with positive margins. She subsequently underwent definitive robotic hysterectomy and bilateral salpingectomy with ovarian preservation. She was diagnosed with a stage IB low-grade ESS. She is currently undergoing observation. Discussion of classification, surgical options, and adjuvant therapy is presented.
