A 61 years old male patient suffering of dyspnea with right upper lobe apical lung tumor- admitted after the complaints had not been ended and the diagnosis could not be obtained from the medical workups performed in another hospital. Lung adenocarcinoma was diagnosed by TTFNAB. 6 cures of carboplatin, pemetrexed was given. The patient admitted with stomach ache and diarrhea. In PET-BT; peritoneal involvement was detected in the peritoneal fatty tissue adjacent to the newly determined anterior abdominal wall, with located 7.8 cm long axis. CK-7 and TTF-1 (+) and CK-20 (-) were seen in the biopsy specimen taken from that region as seen in the specimen taken from the primary mass. It was considered as lung adenocarcinoma metastasis. 10 days palliative radiotherapy was planned for the patient, who still had complaints after second line docetaxel treatment. Peritoneal metastasis is a very rare metastasis in lung cancer. Immunostaining of pathologicspecimens provides a differential diagnosis of metastases caused by the primary tumor or other organs. It is very difficult to diagnose the peritoneal metastasis since peritoneal metastasis of the lung carcinoma is usually asymptomatic. However, it may cause serious complications such as stomach ache, diarrhea or constipation as well as intestinal perforation. Treatment is mostly palliative. Besides surgery and chemotherapy, radiotherapy can be considered as a palliative treatment option for patients with severe symptoms. Peritoneal metastasis is an indicator of poor prognostic and may cause severe mortality and morbidity.
The metastasis of laryngeal carcinoma to skin is very rare. The distant metastasis of head and neck squamous carcinomas involve lungs, liver and bone. We present a 61 year old male patient treated with total laryngectomy and bilateral type 3 modified radical neck dissection due to transglottic laryngeal carcinoma. The patient developed metastatic subcutaneous nodules in the skin of the scalp after eight month of postoperative radiotherapy.
TR Akciğer kanserinin patogenezinde rol oynayan immün hücrelerden biri, doğal öldürücü (NK) hücrelerdir ve bu hücreler, akciğer kanserinde terapötik uygulamalar için yeni hedeflerdir. NK hücre temelli immünoterapinin akciğer kanseri sağ kalımını nasıl etkilediğine odaklanarak, akciğer kanseri üzerine uygulamaları hakkındaki güncel literatürü özetlenmektir. NK hücrelerinin sitolitik potansiyeli, akciğer kanserinde azalır, NK hücre fonksiyonunun iyileştirilmesinin, tümör regresyonuna neden olabileceğini düşündürmektedir. IL-2, IL-12 ve IL-15, NK-92 hücre çizgileri ve allojenik NK hücre immünoterapisini içeren sitokinler gibi NK hücre bazlı yeni tedaviler üzerinde yapılan son klinik çalışmalar, akciğer kanseri sağ kalımı üzerinde daha az yan etkiye sebep olan umut verici sonuçlar göstermiştir. NK hücre hedefleme stratejisi henüz akciğer kanseri tedavisi için onaylanmamıştır. Akciğer kanseri patogenezinde NK hücrelerinin rolüne odaklanan daha fazla klinik çalışma, akciğer kanserinin tedavisi için yeni NK hücre bazlı terapötik yaklaşımlar geliştirmeye hedeflenmiştir. ENG One of the immune cells involved in the pathogenesis of lung cancer is natural killer (NK) cells, which are new targets for therapeutic applications in lung cancer. To summarize the current literature on lung cancer applications, focusing on how NK cell-based immunotherapy affects lung cancer survival. The cytolytic potential of NK cells decreases in lung cancer, suggesting that improvement of NK cell function may lead to tumor regression. Recent clinical studies on NK cell-based new therapies such as IL-2, IL-12, and IL-15, NK-92 cell lines, and cytokines including allogeneic NK cell immunotherapy have shown promising results that have a less adverse effect on lung cancer survival. The NK cell targeting strategy has not yet been approved for the treatment of lung cancer. More clinical trials focusing on the role of NK cells in the pathogenesis of lung cancer are aimed to develop new NK cell-based therapeutic approaches for the treatment of lung cancer.
Akci¤er kanserlerinde cerrahi tedavi, uzun bir sa¤kal›m ve kürabilite sa¤lama aç›s›ndan önemli bir seçenektir. Hastanemizin Gö¤üs Hastal›klar› ve Gö¤üs Cerrahisi Kliniklerinde 2004-2007 y›llar› aras›nda 396 hastaya akci¤er kanseri tan›s› kondu. Ancak bu hastalar›n sadece 45'ine (%11.3) cerrahi tedavi uygulanabildi. Hastalar›n 2'si kad›n, 43'ü erkek ve ortalama yafl 61 (38-74) idi. Ameliyat öncesi dönemde hastalar›n 28'inde (%62. 3) fiber optik bronkoskopi ile, 4'ünde (%8.8) rijit bronkoskopi ile, 7'sinde (%15.5) transtorasik i¤ne aspirasyon biyopsisi ile, 6 's›nda (%13.5) ise aç›k akci¤er biyopsisi ile tan› konuldu. Ameliyat öncesi histopatolojik inceleme ile 38 hastaya küçük hücreli d›fl› akci¤er kanseri (KHDAK), bir hastaya küçük hücreli akci¤er kanseri tan›s› kondu. Alt› hastada ise KHDAK tan›s› aç›k akci¤er biyopsisi ile kondu. Evrelendirme amac› ile 41 hastaya (%91) mediastinoskopi ve ek olarak 5 hastaya (%11. 1) anterior mediastinotomi yap›ld›. Medi...
