肺腺癌で昨年12月に右上葉切除、同時にリンパ節切除をしました。 なお、手術前に数回のCT,脳のMRI,PET-CT

2011 IASLC/ATS/ERS classification of adenocarcinomaによればあなたの場合は次の分類のいずれかにあたります。病理検査でその中に粘液(mucinous lesions)があった場合はその最初の分類、粘液(mucinous lesions)がなく浸潤(invasion)が認められた場合は2番目の分類になります。粘液、浸潤ともにCT上で白く見えます。lepidic growth patternはCT上でスリガラス様に見えます。癌の大きさ23 mm、約8割がすりガラス状で2割が白いとのことですからその粘液、または浸潤は4.6 mmとなり5 mm未満です。完全に手術で切除できた場合はその生存率は粘液であれば100%、浸潤であれば100%に近いといえます。担当医に病理検査で粘液、浸潤について尋ねてはどうかと思います。
Adenocarcinoma in situ (AIS) is a localized (≤3 cm) adenocarcinoma in which growth is restricted to tumor cells growing along alveolar structures (lepidic growth pattern) and lacks any component of invasion. Most AIS tumors are nonmucinous (picture 8). Mucinous lesions comprise a small subset of such tumors (picture 9). Observational studies indicate that AIS has a 100 percent cancer-specific survival if completely resected. AIS was previously categorized as bronchioloalveolar carcinoma in the 2004 WHO system.
Minimally invasive adenocarcinoma is a small, solitary adenocarcinoma (≤3 cm) with a predominantly lepidic growth pattern and less than or equal to 5 mm invasion. Most but not all of these lesions are nonmucinous (picture 10 and picture 11). The cancer-free survival in these patients should approach 100 percent with complete surgical resection, based upon observational studies.
