PURPOSE: Systemic chemotherapy (SC) before surgery is a potential treatment to improve survival in patients with advanced rectal cancer. However, the impact of SC on lateral lymph nodes (LLNs) remains unclear. METHODS: A total of 78 patients with stage II/III low rectal cancer, who received 3-month oxaliplatin-based SC followed by LLN dissection (LLND) in principle, were analysed retrospectively. "Total lateral lymph node metastases (tLLNMs)" was defined as having either pathological LLNMs (pLLNMs) or lateral local recurrences (LLRs). Patients with the maximum short-axis size of LLNs ≥ 7 mm were classified into the swollen group (n = 21). RESULTS: In the total cohort, tLLNMs included 6 pLLNMs (7.7%) and 2 LLRs (2.6%). In the non-swollen group, no patients had pLLNMs, but one had LLR (1.8%). In the swollen group, pLLNMs and LLRs were detected in 6 (28.6%) and 1 (4.8%), respectively. The swollen group was an independent risk factor for tLLNMs (P < 0.001), leading to the significantly worse 5-year relapse-free survival (RFS) of 52.4% than the others. CONCLUSION: For patients without swollen LLNs, SC could allow for omission both of lateral irradiation and LLND. For patients with swollen LLNs, the lateral local control was favourable after SC and LLND without chemoradiotherapy (CRT); however, oxaliplatin-based SC might be insufficient to improve survival, requiring more intensive chemotherapy. CRT should be indicated according to the other risk factors of central local recurrence, although the swollen LLNs should be removed.

LESSONS LEARNED: Two courses of neoadjuvant therapy using S-1 plus cisplatin for clinical stage III esophageal squamous cell carcinoma did not achieve expected response rate according to endoscopic evaluation of primary tumors. Subsequent esophagectomy was safely performed. BACKGROUND: In Japan, esophagectomy after two courses of 5-fluorouracil plus cisplatin is regarded a standard strategy for treating stage II or III esophageal squamous cell carcinoma (ESCC). However, 5-fluorouracil plus cisplatin does not benefit cohorts with clinical stage III ESCC, suggesting the need for a more effective regimen. METHODS: A single-arm, open-label phase II trial was conducted to evaluate the safety and efficacy of two courses of neoadjuvant chemotherapy using S-1 plus cisplatin (NAC-SP) for clinical stage III ESCC. The primary endpoint was overall response rate as defined by endoscopic evaluation of primary tumors. RESULTS: We enrolled 26 patients. The completion rate for the two courses of NAC-SP was 61.5%. Grade 3 or higher adverse events were experienced by 38.4% of patients. The treatment response rate according to endoscopic findings, acquired before the second course, was 34.6% and below the expected level (55.0%). The morbidity rate of patients who underwent radical subtotal esophagectomy (96.2%) was 32.0%. Repeat surgery was unnecessary, and surgery-associated deaths did not occur. The 5-year progression-free survival (PFS) and overall survival (OS) rates were 84.6% and 92.2%, respectively. CONCLUSION: We demonstrate safety of NAC-SP, but not its efficacy, for patients with clinical stage III ESCC. Subsequent esophagectomy was safely performed.

本邦での遠隔転移を伴わない局所進行大腸癌の標準治療は手術+術後補助化学療法であるものの,その治療成績が満足できるものとはいい難い.一方,近年の著しい薬物療法の進歩を背景に,術前化学療法(NAC)は日常臨床の中で徐々に普及しているが,その長期成績は明らかでない.直腸癌に対する術前化学療法(NAC)は欧米では放射線化学療法(CRT)を省略することになり,高リスク症例では受け入れられ難い.しかし,術前治療を一般的に行って来なかった本邦では,NACは単に術後補助化学療法の前倒しであり,可能な施設に限りがあるCRTと比較して,多くの施設で受け入れられやすい.NACはCRTと比較して局所効果はやや劣るものの,生存率は遜色ない.今後は,リスク分類により個別化治療を提供していく必要がある.(著者抄録)

BACKGROUND: Recurrence after radical resection of esophageal squamous cell carcinoma (ESCC) is common. Limited evidence is available about the differences in clinical characteristics, risk factors, and prognostic significance between nodal and distant recurrence of thoracic ESCC. PATIENTS AND METHODS: We retrospectively analyzed 341 patients who underwent radical resection of thoracic ESCC and experienced (1) initial recurrence only in lymph nodes (n = 39), (2) recurrence only at distant organs (n = 57), or (3) no recurrences (n = 245) after follow-up ≥ 24 months. Clinicopathological characteristics, survival times, and risk factors were compared between the nodal and distant recurrence groups. RESULTS: The median follow-up time was 57.8 months. Metastasectomy as initial treatment for the recurrence was performed for six (15.4%) patients in the nodal recurrence group and one patient in the distant recurrence group. Compared with the nodal recurrence group, patients with distant recurrence had significantly shorter disease-free survival [hazard ratio (HR) 1.68, 95% confidence interval (CI) 1.10-2.57, P = 0.0169], postrecurrence survival (HR 1.77, 95% CI 1.01-3.10, P = 0.0476), and overall survival (HR 1.98, 95% CI 1.12-3.51, P = 0.0193). The distant recurrence group had significantly larger macroscopic tumor size and more advanced pathological T stage than the nodal recurrence group, whereas preoperative treatment, tumor location, number of fields dissected, tumor differentiation, lymphatic involvement, and vessel invasion were not significantly different between the two groups. CONCLUSIONS: Survival times and recurrence risk factors differed between patients with nodal and distant recurrence after radical resection of thoracic ESCC.
