An improved approach to histofluorescence using the SPG method for tissue monoamines.

A modification of the SPG histofluorescence method for the visualization of monoamines in tissues using cryostat sections is described. This modification has let to consistent standardization of the fluorescent intensity from one tissue section to another while also eliminating a cumbersome step in the procedure. The present procedure results in highly rapid and sensitive visualization of dopamine-, noradrenaline- and serotonin-containing neurons and their axonal varicosities. Processing time from fresh tissue to microscopic examination requires less than 15 min.

Lymph node invasion in hypopharynx and lateral epilarynx carcinoma: a prognostic factor.

Hypopharynx (HC: pyriform fossa, postcricoïd area, and posterior wall) and lateral epilarynx carcinomas (LEC: aryepiglottic fold, pharyngoepiglottic fold, and arytenoïd) have a high tendency to cervical lymph node invasion. Such nodal extension is a well-known prognostic factor. This study is based on a retrospective review of 884 clinical records of previously untreated HC or LEC. Seventy percent of patients revealed palpable nodes at their first examination, with a higher percentage for HC (73%) than LEC (62%). The 5-year survival rate was divided by three in the presence of contralateral, bilateral, or fixed nodes, or in cases of nodes exceeding 3 cm. Multiple positive nodes, extracapsular spread, or lower-neck positive nodes significantly decreased survival, doubled the number of neck recurrences, and tripled the number of distant metastases while control at the primary site remained unvaried.
