2 In NSCLC patients with N2 disease identified preoperatively (IIIA3), induction therapy followed by surgery is not recommended except as part of a clinical trial. 2

6 Yeniden evrelemede PET-CT
On the basis of these results, we could not recommend PET after induction therapy as a reliable indicator of surgical resection in patients with mediastinal clearance nor as a means of avoiding thoracotomy in those with persistent mediastinal LN disease.

11 The positive predictive value of PET-CT for persistent mediastinal LN metastasis and for the risk of an incomplete resection was high. Our study indicates that PET-CT may be useful in determining the operability after induction chemotherapy for N2 disease. 11

When the maxSUV of a node that was involved initially with metastatic cancer decreased by 50% or more, it is highly likely that the node has been rendered benign by the neoadjuvant therapy. A persistently high maxSUV of an initially involved mediastinal node should not be perceived as evidence of residual disease, but rather only as an indication for a repeat biopsy of the node.

Mediastinotomi In patients with suspected left upper lobe lung cancer and otherwise normal computed tomography scan results, anterior mediastinotomy does not significantly reduce the rate of preventable thoracotomy. Nechala P et al Ann Thorac Surg Dec;82(6): Retrospective analysis of the clinical performance of anterior mediastinotomy.

32 Mediastinotomy Mediastinotomy may be necessary to obtain tissue diagnosis in inoperable cases or for the assessment of resectability of left upper lobe tumours

33 SONUÇ Minimally invasive procedures, such as EBUS-TBNA and EUS-NA may be alternatively used for mediastinal staging, but mediastinoscopy or remediastinoscopy should be preferably reserved for restaging De Leyn P, Lardinois D, Van Schil P, Rami-Porta R, Passlick B, Zielinski M, Waller D, Lerut T, Weder W, ESTS European trends in preoperative and intra-operative nodal staging: ESTS guidelines.

34 İndüksiyon Tedavisi Sonrası Mediastinal Yeniden Evreleme Sorular
İT öncesi tüm hastalar sadece mediastinoskopi ile mi evrelenebilir? İT sonrası PET-CT yeterli midir? İT sonrası histolojik doğrulama her zaman gerekli midir? Histolojik doğrulama için tek alternatif remediastinoskopi midir? Remediastinoskopi komplikasyonları yüksek bir yöntem midir? Remediastinoskopi standart yolla mı, TEMLA ile mi yapılmalıdır?

İT öncesi tüm hastalar sadece mediastinoskopi ile mi evrelenebilir? VATS, EBUS, EUS, Mediastinotomi İT sonrası PET-CT yeterli midir? Kısmen İT sonrası histolojik doğrulama her zaman gerekli midir? Hayır Histolojik doğrulama için tek yöntem remediastinoskopi midir? VATS, EBUS, EUS, Mediastinotomi Remediastinoskopi komplikasyonları yüksek bir yöntem midir? Hayır Remediastinoskopi standart yolla mı, TEMLA ile mi yapılmalıdır? TEMLA daha iyi.
