Review of Under-Recognized Adjunctive Therapies for Cancer.

Patients and providers may not be aware that several adjunctive measures can significantly improve the quality of life, response to treatment, and possibly outcomes for cancer patients. This manuscript presents a review of practical under-recognized adjunctive therapies that are effective including exercise; stress-reduction techniques such as mindfulness, massage, yoga, Tai Chi, breathing exercises; importance of sleep quality; diet modifications such as calorie restriction at the time of chemotherapy and avoidance of high carbohydrate foods; supplements such as aspirin, green tea, turmeric, and melatonin; and repurposed prescription medications such as metformin and statins. Each recommendation should be tailored to the individual patient to assure no contraindications.

Simultaneously occurring disseminated peritoneal leiomyomatosis and multiple extrauterine adenomyomas following hysterectomy.

Disseminated peritoneal leiomyomatosis (DPL), also known as leiomyomatosis peritonealis disseminata, is a rare condition characterized by multiple benign smooth muscle tumors proliferating along the peritoneal surfaces. In previous case reports, these tumors have been noted to involve the ovaries, round ligaments, bladder, bowel, peritoneum, and mesentery. To date, approximately 150 cases of DPL have been described in the literature. Extrauterine adenomyoma is an even rarer entity, involving benign tumors composed of smooth muscle tissue, endometrial glands, and endometrial stroma arising outside the uterus. Only 22 cases have previously been reported. We describe a woman presenting with both DPL and multiple extrauterine adenomyomas several years after undergoing laparoscopic morcellated hysterectomy.

Phase II study of Vigil® DNA engineered immunotherapy as maintenance in advanced stage ovarian cancer.

OBJECTIVES: The majority of women with Stage III/IV ovarian cancer who achieve clinical complete response with frontline standard of care will relapse within 2years. Vigil immunotherapy, a GMCSF/bi-shRNA furin DNA engineered autologous tumor cell (EATC) product, demonstrated safety and induction of circulating activated T-cells against autologous tumor in Phase I trial Senzer et al. (2012, 2013) . Our objectives for this study include evaluation of safety, immune response and recurrence free survival (RFS). METHODS: This is a Phase II crossover trial of Vigil (1.0×107 cells/intradermal injection/month for 4 to 12 doses) in Stage III/IV ovarian cancer patients achieving cCR (normal imaging, CA-125≤35units/ml, physical exam, and no symptoms suggestive of the presence of active disease) following primary surgical debulking and carboplatin/paclitaxel adjuvant or neoadjuvant chemotherapy. Patients received Vigil or standard of care during the maintenance period. RESULTS: Forty-two patients were entered into trial, 31 received Vigil and 11 received standard of care. No≥Grade 3 toxicity related to product was observed. A marked induction of circulating activated T-cell population was observed against individual, pre-processed autologous tumor in the Vigil arm as compared to pre-Vigil baseline using IFNγ ELISPOT response (30/31 negative ELISPOT pre Vigil to 31/31 positive ELISPOT post Vigil, median 134 spots). Moreover, in correlation with ELISPOT response, RFS from time of procurement was improved (mean 826days/median 604days in the Vigil arm from mean 481days/median 377days in the control arm, p=0.033). CONCLUSION: In conjunction with the demonstrated safety, the high rate of induction of T-cell activation and correlation with improvement in RFS justify further Phase II/III assessment of Vigil.

Malignant transformation of endometriosis within the urinary bladder.

Although endometriosis of the pelvic organs is common, endometriosis of the urinary bladder is extremely rare. Malignant transformation of atypical endometriotic foci is an uncommon but well-documented sequela, occurring in approximately 1% of cases. This article reports the fourth case in the English literature of clear cell carcinoma arising from foci of endometriosis within the posterior bladder wall.

A phase II, single-arm study of the anti-α5ß1 integrin antibody volociximab as monotherapy in patients with platinum-resistant advanced epithelial ovarian or primary peritoneal cancer.

OBJECTIVE: This phase II, multicenter, single-arm, two-stage study in platinum-resistant, advanced epithelial ovarian or primary peritoneal cancer evaluated the efficacy, safety, and tolerability of weekly single-agent volociximab. Pharmacokinetic/pharmacodynamic (PK/PD) studies were also performed. METHODS: Sixteen patients were enrolled in Stage 1. Volociximab was administered at 15mg/kg IV qwk until progression of disease or drug intolerability. Tumor response was assessed every 8weeks. Serum samples for PK or whole blood for the evaluation of circulating tumor cells, endothelial cells, and endothelial progenitor cells were obtained on Days 1, 8, 15, 29, and 50. Ascites from one patient was collected for volociximab concentration analysis. Archived tumor tissue was analyzed by immunohistochemistry (IHC) for α5 integrin expression. RESULTS: Safety data are available on all 16 patients; 14 were evaluable for efficacy. One patient had stable disease at 8weeks. The remaining 13 progressed on treatment. Twelve patients (75%) experienced study-related adverse events (AEs); the most common (≥20%) were headache and fatigue. Three patients experienced possible study-related serious AEs (SAEs): reversible posterior leukoencephalopathy syndrome, pulmonary embolism, and hyponatremia. Peak serum concentrations of volociximab increased 2-3 fold from Day 1 to Day 50. Clinically relevant trough levels were achieved (>150µg/mL). IHC analysis of archived tumor sections showed low-to-moderate expression of α5 integrin on all ovarian cancer tissue evaluated. CONCLUSION: Despite insufficient clinical activity in this refractory patient population to continue the study, weekly volociximab was well tolerated, and the gained understanding of the mechanism of action of volociximab will inform future development efforts.

Steep your genes in health: drink tea.

Tea, one of the most commonly consumed beverages in the world, has many health benefits. Tea polyphenols support health by promoting antioxidant enzymes, promoting apoptosis, preventing angiogenesis, and modulating epigenetic change. Considerable basic science and epidemiologic evidence supports the regular consumption of this tasty, inexpensive beverage.

Phase I study of alternating doublets of topotecan/carboplatin and paclitaxel/carboplatin in patients with newly diagnosed, advanced ovarian cancer.

OBJECTIVE: The aim of this study was to evaluate topotecan with carboplatin in an alternating doublet with carboplatin and paclitaxel in first-line ovarian cancer. METHODS: Patients with newly diagnosed stage III/IV ovarian cancer were studied. The maximum tolerated dose (MTD) of topotecan (cycles 1, 3, 5, 7) in an alternating doublet regimen was determined through standard dose escalation in cohorts of three; doses of carboplatin (area under the curve [AUC] 4 to 5) and paclitaxel (175 mg/m(2), cycles 2, 4, 6, 8) were fixed. Dose-limiting toxicity (DLT) was defined only for cycle 1 as febrile neutropenia, prolonged grade 4 granulocytopenia, grade 4 thrombocytopenia, > or =grade 3 nonhematologic toxicity, or failure to recover in < or =7 days. The use of granulocyte colony-stimulating factor (G-CSF) to permit further dose escalation was also studied. RESULTS: Thirty-seven patients received 142 cycles of topotecan/carboplatin. Hematologic DLTs included grade 4 neutropenia (59 events, 42% of cycles) and thrombocytopenia (32 events, 23% of cycles). Granulocytopenia was generally short-lived, and only 2 cases of febrile neutropenia occurred. The MTD was 1.0 mg/m(2)/day topotecan and carboplatin AUC 4, alternating with 175 mg/m(2) paclitaxel and carboplatin AUC 4. Although G-CSF effectively managed myelosuppression, thrombocytopenia developed in later cycles, limiting further topotecan dose escalation. The median progression-free survival was 20.5 months, and elevated pretreatment CA-125 levels normalized in 29 of 34 (85%) patients. CONCLUSION: The establishment of a reasonably well-tolerated alternating doublet regimen, coupled with evidence of antitumor activity, provides the basis for further investigation of topotecan in first-line therapy of ovarian cancer. Topotecan (1.0 mg/m(2) daily for 3 days) was chosen for further evaluation in a phase II study.
