    Abstract: As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19–free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19–free surgical pathways. Patients who underwent surgery within COVID-19–free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19–free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score–matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19–free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION Within available resources, dedicated COVID-19–free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks.

    Abstract: PURPOSE: To revise the staging system for cutaneous melanoma under the auspices of the American Joint Committee on Cancer (AJCC). MATERIALS AND METHODS: The prognostic factors analysis described in the companion publication (this issue), as well as evidence from the published literature, was used to assemble the tumor-node-metastasis criteria and stage grouping for the melanoma staging system. RESULTS: Major changes include (1) melanoma thickness and ulceration but not level of invasion to be used in the T category (except for T1 melanomas); (2) the number of metastatic lymph nodes rather than their gross dimensions and the delineation of clinically occult (ie, microscopic) versus clinically apparent (ie, macroscopic) nodal metastases to be used in the N category; (3) the site of distant metastases and the presence of elevated serum lactic dehydrogenase to be used in the M category; (4) an upstaging of all patients with stage I, II, and III disease when a primary melanoma is ulcerated; (5) a merging of satellite metastases around a primary melanoma and in-transit metastases into a single staging entity that is grouped into stage III disease; and (6) a new convention for defining clinical and pathologic staging so as to take into account the staging information gained from intraoperative lymphatic mapping and sentinel node biopsy. CONCLUSION: This revision will become official with publication of the sixth edition of the AJCC Cancer Staging Manual in the year 2002.

    Abstract: The previously published single institution randomized prospective trial failed to show superiority in the 5-year biochemical and/or clinical disease failure (BCDF) rate with moderate hypofractionated intensity-modulated radiation therapy (H-IMRT) versus conventionally fractionated IMRT (C-IMRT). We now present 10-year disease outcomes using updated risk groups and definitions of biochemical failure. METHODS Men with protocol-defined intermediate- and high-risk prostate adenocarcinoma were randomly assigned to receive C-IMRT (76 Gy in 38 fractions) or H-IMRT (70.2 Gy in 26 fractions). Men with high-risk disease were all prescribed 24 months of androgen deprivation therapy (ADT) and had lymph node irradiation. Men with intermediate risk were prescribed 4 months of ADT at the discretion of the treating physician. The primary endpoint was cumulative incidence of BCDF. We compared disease outcomes and overall mortality by treatment arm, with sensitivity analyses for National Comprehensive Cancer Network (NCCN) risk group adjustment. RESULTS Overall, 303 assessable men were randomly assigned to C-IMRT or H-IMRT. The median follow-up was 122.9 months. Per updated NCCN risk classification, there were 28 patients (9.2%) with low-risk, 189 (62.4%) with intermediate-risk, and 86 (28.4%) with high-risk prostate cancer. The arms were equally balanced for clinicopathologic factors, except that there were more black patients in the C-IMRT arm (17.8% v 7.3%; P = .02). There was no difference in ADT use ( P = .56). The 10-year cumulative incidence of BCDF was 25.9% in the C-IMRT arm and was 30.6% in the H-IMRT arm (hazard ratio, 1.31; 95% CI, 0.82 to 2.11). The two arms also had similar cumulative 10-year rates of biochemical failure, prostate cancer–specific mortality, and overall mortality; however, the 10-year cumulative incidence of distant metastases was higher in the H-IMRT arm (rate difference, 7.8%; 95% CI, 0.7% to 15.1%). CONCLUSION H-IMRT failed to demonstrate superiority compared with C-IMRT in long-term disease outcomes.

    Abstract: It is clinically challenging to integrate genomic-classifier results that report a numeric risk of recurrence into treatment recommendations for localized prostate cancer, which are founded in the framework of risk groups. We aimed to develop a novel clinical-genomic risk grouping system that can readily be incorporated into treatment guidelines for localized prostate cancer. Materials and Methods Two multicenter cohorts (n = 991) were used for training and validation of the clinical-genomic risk groups, and two additional cohorts (n = 5,937) were used for reclassification analyses. Competing risks analysis was used to estimate the risk of distant metastasis. Time-dependent c-indices were constructed to compare clinicopathologic risk models with the clinical-genomic risk groups. Results With a median follow-up of 8 years for patients in the training cohort, 10-year distant metastasis rates for National Comprehensive Cancer Network (NCCN) low, favorable-intermediate, unfavorable-intermediate, and high-risk were 7.3%, 9.2%, 38.0%, and 39.5%, respectively. In contrast, the three-tier clinical-genomic risk groups had 10-year distant metastasis rates of 3.5%, 29.4%, and 54.6%, for low-, intermediate-, and high-risk, respectively, which were consistent in the validation cohort (0%, 25.9%, and 55.2%, respectively). C-indices for the clinical-genomic risk grouping system (0.84; 95% CI, 0.61 to 0.93) were improved over NCCN (0.73; 95% CI, 0.60 to 0.86) and Cancer of the Prostate Risk Assessment (0.74; 95% CI, 0.65 to 0.84), and 30% of patients using NCCN low/intermediate/high would be reclassified by the new three-tier system and 67% of patients would be reclassified from NCCN six-tier (very-low– to very-high–risk) by the new six-tier system. Conclusion A commercially available genomic classifier in combination with standard clinicopathologic variables can generate a simple-to-use clinical-genomic risk grouping that more accurately identifies patients at low, intermediate, and high risk for metastasis and can be easily incorporated into current guidelines to better risk-stratify patients.

    Abstract: 4003 Background: Level A evidence supports use of CisGem as first-line chemotherapy for ABC; no robust evidence is available for second-line chemotherapy. Methods: Pts diagnosed with ABC with disease progression after prior CisGem were randomised (1:1) to either ASC+mFOLFOX or ASC. Randomisation was stratified by serum albumin levels ( 〈 35 vs ≥35 g/L), platinum sensitivity (determined from first-line CisGem) and disease extent (locally advanced vs metastatic). Pts with ECOG PS0-1, adequate haematological, renal and liver function, and adequate biliary drainage were eligible. Primary end-point was overall survival (OS) (multivariable Cox regression adjusted for stratification factors); sample size: 162 pts delivering 148 events were required (80% power; 5% two-sided alpha) for a hypothesised hazard ratio (HR) of 0.63. Assumed median survival for ASC was 4 months. Results: 162 pts (81 in each arm) were randomised (27 March ‘14 - 04 Jan ‘18); median age 65 yrs (range 26-84); sex: 80 (49%) male, 82 (51%) female; primary site: intrahepatic 72 (44%), extrahepatic 45 (28%), gallbladder 34 (21%) and ampullary 11 (7%). Baseline characteristics were balanced between arms except platinum sensitivity (ASC+mFOLFOX 27 pts (33%); ASC 34 pts (42%)). After 150 OS events, the adjusted HR was 0.69 (95% CI 0.50-0.97; p = 0.031; ASC+mFOLFOX vs ASC). Median OS (months (m)), 6m and 12m OS-rate (%) were 6.2m, 50.6% and 25.9% for the ASC+mFOLFOX and 5.3m, 35.5%, 11.4% for the ASC arm, respectively. Grade 3/4 toxicities were reported in 48 (59%) and 32 (39%) pts in the ASC+mFOLFOX and ASC arm, respectively; these were balanced between arms except for fatigue and neutropenia (more frequent in ASC+mFOLFOX arm); data cleaning is ongoing. No chemotherapy-related deaths were reported. Conclusion: Survival with ASC was greater than assumed; ASC+mFOLFOX improved OS after progression to CisGem with a clinically meaningful increase in 6m and 12m OS rate. ASC+mFOLFOX should become standard of care in second-line for ABC. Clinical trial information: NCT01926236.

    Abstract: LBA9000 Background: Atezolizumab (atezo; anti–PD-L1) demonstrated OS benefit vs docetaxel in 2L+ NSCLC regardless of PD-L1 status or tumor histology. Because cytotoxic agents can exhibit positive immunomodulatory effects, combining atezo with chemotherapy may further improve outcomes. IMpower131 (NCT02367794) was designed to evaluate atezo + carboplatin (carbo) + paclitaxel (pac) or nab-paclitaxel (nab-pac) in 1L stage IV squamous NSCLC. Methods: Patients (pts) were randomized 1:1:1 to Arm A (atezo 1200 mg q3w + carbo AUC 6 q3w + pac 200 mg/m 2 q3w), Arm B (atezo + carbo + nab-pac 100 mg/m 2 weekly) or Arm C (carbo + nab-pac). Pts received chemotherapy for 4 or 6 cycles and atezo until loss of clinical benefit. We present the primary analysis of investigator (INV)-assessed PFS per RECIST v1.1 in the ITT population for Arm B vs Arm C. Data cutoff: 22 January 2018. Results: 338 pts (Arm A), 343 pts (Arm B) and 340 pts (Arm C) were enrolled. Minimum follow-up was 9.8 mo. INV-assessed median PFS was 6.3 mo in Arm B vs 5.6 mo in Arm C (HR, 0.715; 95% CI: 0.603, 0.848; P = 0.0001). PFS benefit was enriched in all PD-L1–positive IHC subgroups and was most pronounced in TC3 or IC3. AEs related to any treatment (TRAEs) were 91.3% (Arm A), 94.6% (Arm B) and 90.7% (Arm C); Grade 3-4 TRAEs were 42.8% (Arm A), 68.0% (Arm B) and 56.9% (Arm C); serious TRAEs were 22.3% (Arm A), 20.4% (Arm B) and 10.5% (Arm C). Preliminary OS data will be presented. Conclusions: IMpower131 met its co-primary endpoint of INV-assessed PFS in the ITT population in Arm B vs Arm C. The safety profile of atezo + carbo + nab-pac or pac was consistent with the known risks of the individual treatment components; no new safety signals were identified. Clinical trial information: NCT02367794. [Table: see text]

    Abstract: 173 Background: Radical prostatectomy (RP) is a primary treatment option for men with intermediate and high risk prostate cancer. Though many will be effectively cured with local therapy alone, these men are by definition at higher risk of adverse pathologic findings and clinical disease recurrence. The Decipher test has been previously shown to predict metastatic progression in cohorts that included adjuvant and salvage therapy after RP. Here we evaluate Decipher in a natural history cohort of at risk men who received no additional treatment until the time of metastatic progression. Methods: Men with NCCN intermediate or high risk localized prostate cancer treated with RP at the Johns Hopkins Medical Institute (1992-2010) with at least 5 years of post-operative follow up were identified. Only men with initial undetectable PSA after surgery and who received no therapy prior to metastasis detection were included (n=765). A case-cohort design was used to randomly sample the cohort. The highest Gleason grade cancer tissue was used for RNA extraction and Decipher genomic classifier (GC) scores were calculated with a locked 22-biomarker signature and algorithm. Results: GC results were obtained for 260 patients, 28% had positive margins, 77% had EPE, 28% had SVI, 20% had lymph node invasion and 36% had Gleason ≥8 disease. Median follow up was 9 (IQR 6-12) years and at 15 years post RP the cumulative incidence of BCR, metastasis and prostate cancer specific death was 38%, 21% and 9%. Median GC score was 0.34 (IQR: 0.22-0.52) and was significantly higher among men experiencing metastatic progression during follow up (0.47 vs 0.28 respectively p 〈 0.001). In UVA and MVA (adjusting for clinical covariates), GC had an HR of 1.48 (95% CI: 1.30-1.69, p 〈 0.001) and 1.37 (95% CI: 1.21-1.55, p 〈 0.001) per 10% increase, respectively. Conclusions: The majority of the men in this study had excellent long-term outcomes with surgery alone. Elevated Decipher scores correlated with metastatic events, independent of clinical risk factors. Use of Decipher may allow for selection of candidates for immediate vs. delayed adjuvant or salvage therapy following prostatectomy.

    Abstract: 35 Background: A high mutation burden a biomarker of response to immune checkpoint therapy in melanoma, non-small cell lung cancer, and colorectal cancer. It is unknown whether mutation burden is predictive of response in other cancer types, and whether it is identifiable using available clinical assays. Methods: Using data for 10,745 tumors from 33 solid cancer types in TCGA, we looked for a mutation burden threshold (iCAM) in each cancer type associated with gene expression signatures of a blocked immune response of robust CD8 + T cell response and up-regulation of immune checkpoint genes. Results: A unique iCAM threshold was identified in nine cancers: melanoma and lung, colon, endometrial, and gastric adenocarcinoma; serous ovarian, bladder urothelial, cervical, and ER+ HER2− breast cancer. iCAM thresholds applied to published clinical data for patients treated with immune checkpoint therapy showed that iCAM+ patients had significantly better response. iCAM+ tumors can be identified from clinical-grade NGS assays with high accuracy . In a prospective melanoma cohort of patients treated with anti- PD-1 patients with iCAM+ tumors had significantly better objective response rates, progression free survival, and overall survival compared patients to iCAM− tumors. Pattern of somatic mutations were different in iCAM+ and iCAM− tumors, suggesting different mechanism of carcinogenesis in iCAM+ versus iCAM− tumors. Higher fractions of leukocytes were NK (Natural Killer) cells and macrophages were M1 polarized, and a lower fraction of T cells were regulatory T cells in iCAM+ tumors compared to iCAM− tumors. Over 75% of the genes significantly up-regulated in iCAM+ tumors in every cancer types were in the immune response pathway, confirming immune response to be the main differentiator in iCAM+ veruss iCAM− tumors. Conclusions: In nine cancer types, a clinically useful mutation burden threshold (iCAM) associated with gene expression signatures of blocked immune response can identify likely responders to immune checkpoint therapy, and iCAM status is identifiable using currently available clinical NGS assays.

OPTiM was a randomized, phase 3 trial that showed improved durable response rate (DRR) with T-VEC vs GM-CSF in pts with unresectable melanoma with regional or distant metastases (16.3% vs 2.1%, p 〈 0.001). Treatment benefit of T-VEC on DRR and overall survival (OS) was greater in stage IIIB-IVM1a vs IVM1b-IVM1c melanoma. This is the first report of PFS for T-VEC vs GM-CSF. Methods: OPTiM included pts ≥18 yrs with unresectable stage IIIB-IV melanoma; ≥1 injectable cutaneous, subcutaneous (SC), or nodal lesion; ECOG ≤1; LDH ≤1.5 ULN; ≤3 visceral metastases (excluding lung) with none 〉 3 cm. Pts were randomized 2:1 to receive intralesional T-VEC or SC GM-CSF. The primary endpoint was DRR (partial or complete response continuously for ≥6 mo starting within 12 mo) and reported previously. In this post hoc analysis, PFS was evaluated overall and by disease stage. Results: This analysis included 436 pts: 295 (68%) T-VEC, 141 (32%) GM-CSF; 57% men; 63 yr median age; 57% stage IIIB-IVM1a, 43% stage IVM1b-IVM1c. In the intention to treat set, T-VEC significantly improved PFS (HR: 0.68, 95% CI: 0.54, 0.85, unstratified log-rank p 〈 0.001). In stage IIIB-IVM1a, PFS favored the T-VEC arm vs the GM-CSF arm (HR: 0.60, 95% CI: 0.44, 0.80, unstratified log-rank p 〈 0.001). No treatment difference was seen in stage IVM1b-IVM1c (HR: 0.81, 95% CI: 0.57, 1.15, unstratified log-rank p = 0.199). Overall, the 12 mo PFS rate for T-VEC was 14.4% (95% CI: 10.5, 18.8) and GM -CSF was 4.6% (95% CI: 1.6, 10.2). In stage IIIB-IVM1a, the 12 mo PFS rate for T-VEC was 19.9% (95% CI: 14.0, 26.6) and GM-CSF was 3.2% (95% CI: 0.6, 9.9). In stage IVM1b-IVM1c, the 12 mo PFS rate for T-VEC was 7.4% (95% CI: 3.5, 13.2) and GM-CSF was 8.0% (95% CI: 1.9, 20.1). Conclusions: T-VEC demonstrated an improvement in PFS vs GM-CSF, driven primarily by pts with stage IIIB-IVM1a melanoma. This is consistent with previous data showing more pronounced OS benefit with T-VEC and greater efficacy with other immunotherapies in early metastatic disease.
