To study the high-risk histopathology features of retinoblastoma based on age at primary enucleation. Retrospective study of 616 patients. The mean age at presentation and primary enucleation for retinoblastoma was 34 months (median, 28 months; range, <1–455 months). Of these cases, 128 (21%) were aged ≤1 year, 149 (24%) were in the age group of 1–2 years, 117 (19%) in 2–3 years, 104 (17%) in 3–4 years, and 118 (19%) were >4 years of age at the time of enucleation. Bilateral retinoblastoma (34%; p < 0.0001) and buphthalmos (20%; p < 0.0001) were more common in children ≤1 year of age. Anterior chamber pseudohypopyon (15%; p < 0.0001) and vitreous seeds (53%; p < 0.0001) were more common in children aged >4 years. Based on 8th edition American Joint Committee on Cancer staging system, pT3 was less common in children ≤1 year of age (13%; p < 0.001). Based on histopathology, 38% patients had high-risk features including 24% children aged ≤1 year, 42% in the age group of 1–2 years, 34% in 2–3 years age group, 45% in 3–4 years age group, and 48% patients were >4 years of age. Post-laminar optic nerve infiltration (6%; p = 0.02) and massive choroidal infiltration (9%; p = 0.04) was least common in children ≤1 year of age. Over a mean follow-up period of 52 months (median, 36 months; range, <1–218 months), systemic metastasis and death occurred in 9% patients despite adjuvant systemic chemotherapy. The predominant high-risk histopathology feature of retinoblastoma varies with age at primary enucleation.

基于初次摘除术年龄的高危视网膜母细胞瘤:一项对 616 只眼的研究

研究基于初次摘除术年龄的视网膜母细胞瘤的高危组织病理学特征。616 例患者的回顾性研究。视网膜母细胞瘤就诊和初次摘除术的平均年龄为 34 个月(中位数,28 个月;范围,<1-455 个月)。在这些病例中,128 (21%) 名年龄≤1 岁,149 (24%) 名在 1-2 岁年龄组,117 (19%) 名在 2-3 岁,104 (17%) 名在 3- 4 岁,118 人 (19%) 在摘除时年龄 > 4 岁。双侧视网膜母细胞瘤 (34%; p < 0.0001) 和眼眶 (20%; p < 0.0001) 在 1 岁以下儿童中更为常见。前房假性前房积脓 (15%; p < 0.0001) 和玻璃体种子 (53%; p < 0.0001) 在 4 岁以上的儿童中更常见。基于第 8 版美国癌症联合委员会分期系统,pT3 在 ≤ 1 岁的儿童中不太常见(13%;p < 0.001)。根据组织病理学,38% 的患者具有高危特征,包括 24% ≤1 岁的儿童,42% 在 1-2 岁年龄组,34% 在 2-3 岁年龄组,45% 在 3-4 岁年龄组年龄组,48% 的患者年龄 > 4 岁。层流后视神经浸润 (6%; p = 0.02) 和大量脉络膜浸润 (9%; p = 0.04) 在 1 岁以下儿童中最不常见。在平均 52 个月的随访期间(中位数,36 个月;范围,<1-218 个月),尽管进行了辅助全身化疗,仍有 9% 的患者发生了全身转移和死亡。视网膜母细胞瘤的主要高危组织病理学特征随初次摘除术的年龄而异。1-2 岁年龄组 42%,2-3 岁年龄组 34%,3-4 岁年龄组 45%,48% 患者>4 岁。层流后视神经浸润 (6%; p = 0.02) 和大量脉络膜浸润 (9%; p = 0.04) 在 1 岁以下儿童中最不常见。在平均 52 个月的随访期间(中位数,36 个月;范围,<1-218 个月),尽管进行了辅助全身化疗,仍有 9% 的患者发生了全身转移和死亡。视网膜母细胞瘤的主要高危组织病理学特征随初次摘除术的年龄而异。1-2 岁年龄组 42%,2-3 岁年龄组 34%,3-4 岁年龄组 45%,48% 患者>4 岁。层流后视神经浸润 (6%; p = 0.02) 和大量脉络膜浸润 (9%; p = 0.04) 在 1 岁以下儿童中最不常见。在平均 52 个月的随访期间(中位数,36 个月;范围,<1-218 个月),尽管进行了辅助全身化疗,仍有 9% 的患者发生了全身转移和死亡。视网膜母细胞瘤的主要高危组织病理学特征随初次摘除术的年龄而异。在平均 52 个月的随访期间(中位数,36 个月;范围,<1-218 个月),尽管进行了辅助全身化疗,仍有 9% 的患者发生了全身转移和死亡。视网膜母细胞瘤的主要高危组织病理学特征随初次摘除术的年龄而异。在平均 52 个月的随访期间(中位数,36 个月;范围,<1-218 个月),尽管进行了辅助全身化疗,仍有 9% 的患者发生了全身转移和死亡。视网膜母细胞瘤的主要高危组织病理学特征随初次摘除术的年龄而异。
