Complete and Durable Response After Radiation Therapy to Primary Tumor Site of a Patient With Metastatic Anorectal Mucosal Melanoma With Oligoprogression on Nivolumab

e21046 Background: Overall survival (OS) for pts with cutaneous melanoma has vastly improved with checkpoint inhibitors (CPI) and targeted therapy (TT), but less is known about outcomes of other rare tumors showing melanocytic differentiation. We examined outcomes for metastatic pts with MSP/CCS at MD Anderson (MDA) to characterize outcomes with contemporary therapies. Methods: Pts with MSP/CCS were identified in the MDA databases. Pts with < 2 visits to MDA or without molecular confirmation of dx were excluded. Log-rank testing was used to compare OS among distributions. Results: A total of 102 MSP/CCS pts were identified. Initial diagnosis was local disease 46%, regional metastases 34%, and systemic metastases 20%. Primary tumor site was lower extremity (LE) 48%, GI tract 29%, upper extremity (UE) 18%. 65 pts were diagnosed with metastatic disease (dz), including 32% with lung-only, 14% liver-only, and 51% with multiple metastatic sites. Median OS from diagnosis of distant metastatic dz was 22 mos (95% CI 16-34 mos). Primary tumor site (GI 46.4 vs. LE 19.1 vs. UE 14.7 mos; p = 0.018) and race (white 26.8 vs. black 6.5 mos, p = 0.019, HR 0.45) were significantly associated with OS from distant metastasis; sex, age, decade of diagnosis, size of primary, and prior treatment with neoadjuvant or adjuvant therapy were not. Treatments for metastatic dz included chemotherapy (n = 29), biochemotherapy (n = 11), biotherapy (n = 5), CPI (n = 11) and TT (n = 19). Median OS was 15.9 mos from start of CPI (range 10.7 to NR) and 16.9 mos from start of TT (range 7.8 to NR). Median OS from metastatic dz for pts not treated with CPI or TT was 17.1 mos (range 12.4 to 32.5), which was not significantly different versus CPI or TT. Duration of response was < 6 mos for 91% pts receiving CPI and 89% pts receiving TT. One pt had a durable response (41.8 mos) to anti-PD1 and one pt had a durable response (24.8 mos) to an AKT inhibitor. Conclusions: While rare responses to CPI and TT were observed, no significant difference was detected in OS compared to traditional therapies in pts with metastatic MSP/CCS. The development of more effective therapies remains an unmet need for this disease.

PURPOSE We designed a protocol to evaluate the possibility of organ preservation in patients with advanced, resectable carcinoma of the head and neck. The regimen consisted of intensive chemotherapy followed by radiation therapy alone for patients with good response to treatment. The end points of the study were response rate, organ preservation, toxicity, and survival. PATIENTS AND METHODS Forty-two eligible patients with carcinoma of the oral cavity, oropharynx, hypopharynx, larynx, and paranasal sinuses were enrolled. Induction chemotherapy consisted of three cycles of mitoguazone, fluorouracil (5-FU), and high-dose continuous infusion cisplatin. Patients who had a complete response to chemotherapy, or whose tumor was downstaged to T1N1, were treated with definitive radiation therapy, to a total dose of 66 to 73.8 Gy. Patients with residual disease greater than T1N1 underwent surgery and postoperative radiation. RESULTS The overall response rate to chemotherapy was 84%, with a 43% complete response rate, and a 68% complete response rate at the primary tumor site. Sixty-nine percent of patients (29 of 42) were initially spared surgery to the primary tumor site, and four of these patients (14%) required neck dissection only, after radiation therapy. These tumor sites included oral cavity, oropharynx, hypopharynx, larynx, and sinuses. Eventually, five of these patients (17%) required salvage surgery and eight patients (28%) had unresectable or metastatic relapses. With a median follow-up duration of 38.5 months, 36% of all patients have had preservation of the primary tumor site and remain disease-free. The median survival duration is 26.8 months. Toxicity was substantial, with a 70% incidence of grade 3 to 4 granulocytopenia and two septic deaths. CONCLUSION Organ preservation without apparent compromise of survival was achieved in patients with selected nonlaryngeal sites of head and neck carcinoma. Larger site-specific trials with less toxic regimens conducted in randomized fashion are required to extend these data.

PURPOSE To examine the effects of lomustine (CCNU), a commonly used nitrosourea, and craniospinal radiation therapy on the subsequent development of restrictive lung disease (RLD) following treatment for malignant brain tumors. PATIENTS AND METHODS Pulmonary function testing with measurement of lung volume, spirometry, and diffusion capacity was performed in 28 patients who had received CCNU and/or radiation therapy as treatment for a malignant brain tumor. The median age at the time of treatment was 11.4 years (range, 3.9 to 36.7) and radiation therapy was completed 6 months to 11.6 years (median, 2.6 years) before testing. Patients were divided into four groups based on prior therapy. Group 1 received involved-field irradiation and a CCNU-containing chemotherapy regimen (n = 7); group 2, craniospinal irradiation with a boost to the primary tumor site and a CCNU-containing chemotherapy regimen (n = 6); group 3, craniospinal irradiation with a boost to the primary tumor site and a non-CCNU-containing chemotherapy regimen (n = 7); and group 4, craniospinal irradiation with a boost to the primary tumor site without chemotherapy (n = 8). RESULTS Fourteen patients (50%) had findings consistent with RLD. One of seven patients (14.3%) who received CCNU without spinal irradiation had RLD, whereas 13 of 21 (61.9%) who received spinal irradiation with or without CCNU had RLD (P = .038), including four of eight patients treated with craniospinal irradiation alone. Logistic regression analysis showed that only spinal irradiation was a significant predictor for RLD. Patients who received spinal irradiation were 4.3 times more likely to have RLD than those who did not receive spinal irradiation. CONCLUSION Spinal irradiation may be a risk factor for the development of RLD.

✓ The authors describe two cases of malignant astrocytomas associated with previous radiation therapy in childhood for intracranial germinoma and craniopharyngioma. In both patients, there was no recurrence at the primary tumor site. Because of a geometric coincidence between the tumor location and the radiation field, radiotherapy was strongly implicated as a cause of these two astrocytomas.

PURPOSE Patients with lymphoblastic non-Hodgkin's lymphoma (LB NHL) were randomized to treatment with either modified LSA2L2 or ADCOMP, which added daunorubicin (DAUN) and asparaginase (L-ASP) to the methotrexate (MTX), cyclophosphamide (CYT), vincristine (VCR), and prednisone (PRED) (COMP) regimen, in a clinical trial to determine the relative effectiveness and toxicity of the two regimens. PATIENTS AND METHODS Patients with LB NHL were eligible for this randomized study if they were less than 22 years of age at diagnosis and had < or = 25% blasts in the bone marrow. Of 307 patients registered, 281 were fully eligible and assessable. Patients were stratified by extent of disease at diagnosis. RESULTS The 5-year event-free survival (EFS) rate for patients with localized disease was 84%, and for patients with disseminated disease, 67%. There were four relapses in 28 patients with localized disease. Two hundred six patients had mediastinal primary tumors and despite local radiation, 34 of 63 failures in these patients involved the primary tumor site with or without other involvement. After adjusting for extent of disease at diagnosis, the regimens did not differ significantly with respect to risk for adverse events. The acute toxicity was primarily neutropenia and thrombocytopenia, with greater initial toxicity in patients on the LSA2L2 regimen. Three patients developed acute myelogenous leukemia. CONCLUSION Long-term EFS in children with LB NHL can be achieved in the majority of patients. Disease progression, which includes recurrence at the primary tumor site, is a major cause of treatment failure in patients with mediastinal presentations. Addition of DAUN and L-ASP to the COMP regimen does not produce a more effective treatment than LSA2L2.

360 Background: Angiogenesis plays an important role in NET development and progression. Axitinib is a potent and selective VEGFR-1,2,3 inhibitor, with proven activity against several vascular-dependent solid tumors. The aim of this randomized, double-blind phase II/III study was to assess the efficacy of axitinib in patients with advanced G1-2 extra-pancreatic NETs. Methods: Eligible pts were randomized (1:1) to receive octreotide LAR (30 mg IM q4w) with axitinib (5 mg BID) or placebo BID until disease progression or unacceptable toxicity. Pteswere stratified by time from diagnosis to study entry ( > or < 12m), primary tumor site (GI tract vs non-GI) and Ki-67 index (< 5% vs > 5%). Prior therapy with SSA, IFN and up to 2 lines of systemic treatment was allowed, but not prior VEGF- or VEGFR-targeted drugs. Clinical and/or radiological disease progression within 12 months prior to study entry was required. The primary endpoint was progression-free survival (PFS). Secondary endpoints included overall survival (OS), time to progression, overall response rate (ORR), duration of response, biochemical response and safety. Results: 256 pts were randomized (106 in the Phase II part, and 150 additional pts in the Phase III part), 126 to axitinib and 130 to placebo. The main characteristics of the study population were: median age 61 years (range: 21-85), 52% male, PS 0-1 (64-35%), G1-2 (29%-71%), primary tumor site GI (40%)-Lung (17%)-Other (32%). Prior therapies included: SSA (46%), everolimus (13%), chemotherapy (13%), TACE (5%) and PRRT (2%). ORR was significantly higher in axitinib- vs placebo-treated patients (17.5% vs 3.8%, p = 0.0004). PFS per investigator assessment also favored axitinib vs placebo-treated patients, although the difference did not reach statistical significance (median PFS 17.2 vs 12.3 months, respectively, HR 0.816, p = 0.169). Grade 3-4 treatment-related AEs occurred more frequently in the axitinib vs placebo arm (52% vs 13.8%), and included hypertension (21% vs 6 %), cardiac disorders (3.2% vs 0.7%), diarrhoea (13% vs 1.5 %), asthenia (9% vs 3%) and nausea&vomiting (2% vs 0.7%). There were 3 treatment-related deaths, 1 in the axitinib arm (cardiac failure) and 2 in the placebo arm (myocardial infarction and hepatorenal syndrome). Conclusions: Although the study failed to demonstrate a significant PFS benefit per investigator assessment, axitinib in combination with octreotide LAR demonstrated activity and had a tolerable safety profile in patients with advanced G1-2 extra-pancreatic NETs. Data base cleaning and central blinded radiological PFS assessment are currently ongoing. Clinical trial information: NCT01744249.
