''Çok düşük riskli mesane kanseri'' Kas-invaziv olmayan mesane kanserlerinde gerçekten yeni bir alt grup mu?
Abstract
Giriş: Düşük
riskli mesane kanserinin klinik sonuçlarını analiz ederek “çok düşük riskli”
mesane kanserinin öngörücü rollerini değerlendirmeyi amaçladık
Gereç
ve yöntem: 2013 ve Aralık 2019 tarihleri arasında düşük riskli NMIBC
tanısı ile tedavi ve takip edilen 32 hasta retrospektif olarak incelendi.
Hastalar tümör büyüklüğüne göre iki prognostik gruba ayrıldı (≤1,0 cm ve
>1,0 cm). İki grup klinik, patolojik bulgular ve nüks, takipte ilerleme
açısından karşılaştırıldı.
Bulgular:
Toplam 32 hasta rekürrens görülme süresine kadar takip edildi. Toplam 14
hastada, tümör boyutu 1 cm altında idi. Tek değişkenli Cox modellemesinde,
sigara içme durumu ve intravezikal mitomisin C (MMC), rekürrens için daha kısa
süre ile anlamlı derecede ilişkiliydi (sırasıyla,
HR 0,103, %95 CI 0,020-0,520, p=0,006; HR 4,264, %95 CI 1,026-17,727, p=0,046).
Tümör boyutunun bağımsız öngörü faktörü olarak rekürrens zamanını etkilemediği
görüldü (p=0,838).
Sonuç:
Düşük
riskli KİOMK tanısı alan hastalarda önerilen çok düşük riskli grup
modellemesinde, 1 cm altı olarak belirlenen grup ile 1 cm üstü tümörlerde
rekürrens açısından anlamlı farklılık izlenmedi.

Is ''Very-low-risk'' really a new subgroup of bladder cancers that are non-muscle-invasive bladder cancer?
Abstract
Introductıon: We
aimed to evaluate the predictive roles of “very-low-risk” bladder cancer by
analyzing the clinical outcomes of low-risk bladder cancer
Materıal and Methods: 32
patients who were treated and followed up between 2013 and December 2019 with
the diagnosis of low-risk NMIBC were retrospectively analyzed. Patients were
divided into two prognostic groups based on tumor size (≤1.0 cm vs >1.0 cm).
Two groups were compared in terms of clinical, pathological findings and
recurrence, progression in follow-up.
Results: A
total of 32 patients were followed up to recurrence time. A total of 14 patients
had tumors that were ≤1,0 cm. Using univariate Cox modeling, smoking status
and Intravesical Mitomycin C (MMC) were significantly associated with shorter
time to recurrence (HR 0.103 95% CI 0.020-0,520, P = 0.006; HR 4.264 95% CI
1.026-17.727, P = 0.046; respectively ) . Tumor size was not significantly
associated with any differences in time to recurrence (P = 0,838).
Conclusion: Lower tumors (≤1.0 cm) are not significantly
associated with shorter time to recurrence compared with larger tumors (>1.0
cm).
