Second Primary Malignancies

4565 Background: Esophageal squamous cell carcinoma (ESCC) is associated with synchronous or metachronous cancer at other primary sites. Previous studies have suggested that patients (pts) with ESCC are still at a high risk of second primary malignancies after definitive therapies. In particular, early-stage ESCCs result in good prognosis, which is associated with a higher risk of second primary malignancies. Methods: The JCOG0502 was a phase III trial, which included a randomized and a non-randomized part and compared esophagectomy with definitive chemoradiotherapy in clinical T1bN0 ESCC. We additionally reviewed data of all pts enrolled in the JCOG0502 for second primary malignancies. Lugol-voiding lesions (LVLs) were assessed in the noncancerous esophageal mucosa before the treatments. Results: Among 379 enrolled pts, 213 pts received esophagectomy and the remaining received chemoradiotherapy. Patient characteristics of overall cohort were as follows: male, 85%; median age, 63 (range, 41–75) years; upper- /middle- /lower thoracic esophagus, 11/63/27%; alcohol consumption history, 79%; smoking history, 66%; prevalence of no LVLs/several LVLs/many LVLs/unknown, 45/36/8/11%. With a median follow-up of 7.1 years, a total of 118 second malignancies were observed in 99 pts (26%). Cumulative incidences of second malignancies after 3, 5, 10 years were 9, 15, 36%, respectively. Most common primary tumor sites were head and neck (35%), followed by stomach (20%) and lung (14%). In multivariable analyses, several LVLs [hazard ratio (HR): 2.24, 95% confidential interval (CI): 1.32–3.81, vs. no LVLs] and many LVLs (HR: 2.88, 95% CI: 1.27–6.52, vs. no LVLs) were significantly associated with the development of second malignancies. Regarding the three most common types of cancers, 62 out of the 77 cancers (81%) were diagnosed in clinical stage 0–I. Seventeen pts died due to second primary malignancies. There were 4 and 3 deaths from head and neck and lung cancer, respectively. Whereas, mortality caused by stomach cancer was not observed. Conclusions: In the JCOG0502, the incidence of second malignancies was high, indicating that careful follow-up is required for ESCC pts even after treatment completion. The presence of LVLs in esophagus was identified as an independent predictive factor for second primary malignancies, which may be useful for surveillance strategies.

Abstract Background Second primary head and neck cancers after endoscopic resection of esophageal squamous cell carcinoma adversely affect patients’ outcomes and the quality of life; however, an adequate surveillance schedule remains unclear. Methods We analyzed 330 patients with early esophageal squamous cell carcinoma who underwent endoscopic resection and were registered in the multicenter cohort study to evaluate adequate surveillance for detection of second primary head and neck cancers. Gastrointestinal endoscopists examined the head and neck regions after 3–6 months of endoscopic resection for esophageal squamous cell carcinoma and subsequently every 6 months. An otolaryngologist also examined the head and neck regions at the time of endoscopic resection for esophageal squamous cell carcinoma and at 12 months intervals thereafter. Results During the median follow-up period of 49.4 months (1.3–81.2 months), 33 second primary head and neck cancers were newly detected in 20 patients (6%). The tumor site was as follows: 22 lesions in the hypopharynx, eight lesions in the oropharynx, two lesions in larynx and one lesion in the oral cavity. The 2-year cumulative incidence rate of second primary head and neck cancers was 3.7%. Among them, 17 patients with 29 lesions were treated by transoral surgery. One patient with two synchronous lesions was treated by radiotherapy. Two lesions in two patients were not detected after biopsy. All patients were cured with preserved laryngeal function. Conclusions Surveillance by gastrointestinal endoscopy every 6 months and surveillance by an otolaryngologist every 12 months could detect second primary head and neck cancers at an early stage, thereby facilitating minimally invasive treatment.

e17032 Background: Cetuximab (CTx) is used in treatment of locally advanced (LAD) head and neck squamous cell carcinoma (HNSCC) in combination with radiotherapy (RT) or in metastatic disease (MD). There is no comparison between CTx plus RT and cisplatin plus RT. Patients treated with CTx in daily clinical practice are frequently different from the selected population treated in clinical trials. There are no biomarkers for efficacy of CTx in HNSCC. EGFR variant 3 mutation (EGFRv3), an extracellular domain mutation of EGFR, has been reported in different frequencies in HNSCC in the last years and its association with prognosis and CTx efficacy is still unknown. Methods: Retrospective review of data from patients with HNSCC treated with CTx at a single institution from 2007 to 2010. We evaluated CTx efficacy and expression of EGFRv3, EGFR, PTEN, CD44 and CD44v6 and their impact in objective response rate (ORR), progression free survival (PFS) and overall survival (OS). Biomarkers were analyzed by immunohistochemistry in tissue microarray. Results: For a median follow-up time of 13 months, 61 patients with LAD treated with RT plus CTx had a median OS of 22.7 months, and a median PFS of 8.0 months. Age adjusted Charlson Comorbidity Index (AA-CCI) and ECOG performance status were the most important predictors of poor prognosis in this population. For a median follow-up time of 10.9 months, 44 patients with MD had a median OS of 13.0 months and a median PFS of 7.0 months, for an ORR of 53.7%. EGFRv3 was expressed in 27.1% of tumor samples and was not associated with any clinical outcome. EGFR positivity was associated to higher ORR in LAD and PTEN negativity was associated with shorter OS in the MD setting. Conclusions: In a non selected population with LAD treatment results with CTx in combination with radiotherapy were worse than expected by the phase III study, median OS 22.7 months vs 49.0 months. This difference may be attributed to different population characteristics with higher ECOG and AA-CCI in our study and warrants an adequate proof of efficacy of CTx in this population. EGFRv3 is present in HNSCC but does not impact prognosis. PTEN and EGFR expression emerged as potential biomarkers in HNSCC patients treated with CTx.

Esophageal squamous cell neoplasms (ESCNs) are the most common second primary neoplasm in patients with head and neck squamous cell carcinoma (HNSCC), and few studies have focused on metachronous ESCNs. We aimed to evaluate the incidence of and risk factors for metachronous ESCNs and to provide a reasonable endoscopic follow-up plan for HNSCC patients. We extended our prospective cohort since October 2008 by recruiting incident HNSCC patients. All enrolled patients were interviewed to collect information on substance use (smoking, alcohol, and betel nut) and esophagogastroduodenoscopy (EGD) with Lugol chromoendoscopy results for synchronous ESCNs soon after HNSCC diagnosis. Endoscopic screenings for metachronous ESCNs were performed 6 to 12 months after the previous examinations. A total of 1042 incident HNSCC patients were enrolled, but only 175 patients met all the criteria and were analyzed. A total of 20 patients had metachronous ESCNs (20/175, 11.4%). Only the initial Lugol-voiding lesion (LVL) classification significantly predicted the development of metachronous ESCNs. Patients with an LVL classification of C/D had a higher risk of developing metachronous ESCNs than those with an LVL classification of A/B (adjusted odds ratio: 5.03, 95% confidence interval: 1.52–16.67). The mean interval for developing metachronous ESCNs was 33 months, but the shortest interval for developing metachronous esophageal squamous cell carcinoma was 12 months. Lugol chromoendoscopy screening among incident HNSCC patients predicts the risk of developing metachronous ESCNs. A closer follow-up with an endoscopy every 6 months is recommended for those with LVL classifications of C and D.

215 Background: Esophageal squamous cell carcinoma (ESCC) is a lethal cancer with a high unmet medical need. Camrelizumab, an anti-PD-1 monoclonal antibody, significantly improved overall survival (OS) and objective response rate (ORR) in Chinese patients (pts) with advanced ESCC compared with chemotherapy, with a manageable safety profile in phase III randomized trial (ESCORT). However, the absolute long-term survival benefiting from PD-1 inhibitors is limited, and new effective treatments are needed. Here, our study aimed to assess the efficacy and safety of combination with camrelizumab and apatinib (VEGFR2 inhibitor) as second-line treatment for advanced ESCC. Methods: This ongoing phase II trial (NCT03736863) in six sites in China enrolled pts aged 18-75 with unresectable locally advanced, locally recurrent, or metastatic ESCC that progressed or were intolerant after first-line chemotherapy, and an ECOG performance status of 0-1. Pts received 200 mg intravenous camrelizumab every two weeks plus 250 mg oral apatinib daily in 4-week cycles until disease progression, unacceptable adverse events (AEs) or withdrawal of consent. The primary endpoint was investigator-assessed ORR. Secondary endpoints included disease control rate (DCR), progression-free survival (PFS) and OS. Results: At data cutoff (Sept 11, 2020), 36 pts were enrolled, 7 females and 29 males, and 25 pts had lymph node metastases. Twelve pts received radiotherapy and 25 underwent surgery. Twenty-five pts were included in the efficacy analysis with median follow-up time of 5.0 months and 36 pts in the safety analysis with median follow-up time of 4.6 months. The primary endpoint ORR without confirmation was 40 % with complete response in two pts (8%) and partial response in eight pts (32%). Thirteen pts (52%) had stable disease, and the DCR was 92%. The median PFS and OS were not reached. A total of 72.2% of pts had AEs, and 30.6% of pts experienced grade 3 AEs. The most common AEs (all grade, grade≥3) were elevated aspartate aminotransferase (30.6%, 19.4%), elevated alanine aminotransferase (30.6%, 13.9%), hypertension (25%, 2.8%),neutrophil (25%, 5.6%), thrombocytopenia (25%, 0%), leukopenia (22.2%, 2.8%), anemia (11.1%, 0%), proteinuria (11.1%, 0%), hematochezia (8.3%, 0%), reactive cutaneous capillary endothelial proliferation (5.6%, 2.8%), pruritus (5.6%, 0%), esophageal fistula (5.6%, 0%), fatigue (2.8%, 0%) and hypothyroidism (2.8%, 0%). Conclusions: This is the first study to explore the combination of PD-1 inhibitor and anti-angiogenesis inhibitor as a second-line treatment for advanced ESCC. Camrelizumab plus apatinib demonstrated encouraging clinical efficacy and acceptable safety as second-line treatment, and might be a favorable option for pts with advanced ESCC. Further phase III randomized trials are warranted. Clinical trial information: NCT03736863.
