Background. To ­review the ­results of com­plete sur­gi­cal resec­tion of pul­mo­nary metas­ta­sis - a ten-­year expe­ri­ence.
Setting. Retrospective anal­y­sis of all ­patients ­with ­lung sec­on­dar­ies who ­received com­plete sur­gi­cal resec­tion of pul­mo­nary metas­ta­ses (­from 1984 to 1995) in Grantham Hospital, Hong Kong. Sixty ­patients ­over a 10-­year peri­od ­were stud­ied.
Methods. Eighty thor­a­cot­o­mies ­were per­formed ­with 88 ­tumour nod­ules ­excised. The fol­low-up peri­od ­ranged ­from 5 ­months to 111 ­months.
Results. Thirteen (14.8%) spec­i­mens ­were ­found to ­have ­tumour ­size great­er ­than 5.0 cm. This may ­reflect ­late detec­tion of met­a­stat­ic ­tumour and prob­ably ­accounts for the high­er per­cent­age of our ­patients receiv­ing ­more ­major ­lung resec­tions (63.3%) ­than ­just ­wedge resec­tions (36.6%). The ­mean sur­vi­val peri­od for the sub­group ­with hepat­o­cel­lu­lar car­ci­no­ma was 28.2 ­months and for the nasoph­a­ryn­geal car­ci­no­ma ­group was 25 ­months. The ­mean sur­vi­val of the ­whole ­group was 26.4 ­months.
Conclusions. The favour­able out­come for hepat­o­cel­lu­lar car­ci­no­ma and nasoph­a­ryn­geal car­ci­no­ma ­could be due to the ­result of selec­tion of ­patients ­with ­more favour­able prog­no­sis for sur­gery. The ­latent peri­od, ­using 12 ­months as a ­break-off ­point, did not ­affect ­patient sur­vi­val in our ­study.
