Discontinuous Involvement of Spermatic Cord Soft Tissue in Testicular Germ Cell Tumors: A Multi-Institution Experience

Introduction/Objective

In the 8th Edition AJCC Cancer Staging Manual, discontinuous involvement of spermatic cord soft tissue (DISC) by testicular germ cell tumors (GCT) is regarded as metastatic deposit (pM1), placing the patient in clinical prognostic stage group (CPSG) III. We conducted a multi-institution study to corroborate or refute the current recommendations. Methods: Thirty-eight cases of GCT with spermatic cord involvement were collected from 13 institutions in Europe, Phillipines and America. Clinical and pathologic data was obtained.

Results

Tumors included 28 (73%) non-seminomatous and 10 (26%) seminomatous GCTs. Mean testicular tumor size was 6.6 cm (range 1.3-18). After review by an uropathologist, cases were classified as cord LVI [T2] (n=3), continuous cord involvement (CCI) [T3] (n=13), and DISC (n=22). Mean cord tumor size for DISC was 0.9 cm (range 0.1-4.5).

CPSG was available for 33 and follow-up (FU) for22 patients with a mean length of FU of 38 months (range 2-144). Seven (39%) DISC patients were CPSG II (regional LN metastases), and 11 (61%) CPSG III (distant metastases). On FU, 5 (45%) DISC patients had no evidence of disease (NED); 6 (55%) were alive with disease (AWD). Three (25%)

CCI patients were CPSG I (local disease), 6 (50%) CPSG II, and 3 (25%) CPSG III. On FU, 6 (60%) CCI patients were NED, 4 (40%) AWD. Cord LVI patients were one in each CPSG. One cord LVI patient was NED, the others were lost at FU. All DISC (100%) patients with available CPSG had advanced disease (CPSG II or III), compared to 75% of CCI, and 67% of cord LVI patients.

Conclusion

Although it did not reach statistical significance (p=0.054; Fisher’s exact test), DISC patients were more likely to have CPSG II and III compared to CCI patients. Our findings suggest a worse behavior in patients with DISC, supporting a higher pathologic stage than CCI.

Congenital lobar emphysema in a Nigerian neonate: a rare cause of neonatal respiratory distress

Congenital lobar emphysema (CLE) is a notable cause of respiratory distress in neonates, however it remains a diagnostic challenge due to inadequate facilities and low level of experience. The management of this condition also is a bigger challenge due to paucity of expertise and relatively non-existent well-equiped neonatal intensive care unit in this part of the world. Here we present the case of a 5- day old baby who presented at Lagoon Hospital, Apapa with history of severe respiratory distress since birth. CT scan of the chest confirmed an emphysematous left upper lobe with contralateral mediastinal shift. The baby had a left posterolateral thoracotomy with left upper lobectomy and thereafter was electively ventillated for forty eight hours in the neonatal intensive unit. He had an uneventful postoperative course and was discharged from the hospital within one week forfollow-up in the clinic.
