If the mediastinal disease is not contiguous, the timing of mediastinal dissection is guided in part by the pathology of the retroperitoneum. This rationale is based on studies evaluating concordance between retroperitoneal and thoracic pathology discussed earlier. KEY POINTS: AUXILIARY PROCEDURES Description of the surgical approach to most supradiaphragmatic disease is beyond the scope of this chapter. However, the surgical approach to and timing of resection of retrocrural disease is often intimately related to RPLND.

The retrocrural space presents a surgical challenge given its anatomic location, and surgical approaches to retrocrural disease have evolved over time. Most of these cases are performed in combination with the thoracic surgery team. At Indiana University, early efforts employed a thoracoabdominal incision or a separate midline laparotomy and posterior thoracotomy.

A more recent breastfeeding hot used for residual lower retrocrural disease is a midline laparotomy employing a transabdominal transdiaphragmatic approach that can be performed at the same time Chlordiazepoxide (Librium)- FDA RPLND (Fig.

This approach was first described by Fadel and associates (2000) in 18 patients who had simultaneous resection of masses located in the retroperitoneum and lower mediastinum.

The rationale for this approach was to minimize the morbidity of a thoracotomy when feasible. Kesler and colleagues (2003) published results on 268 patients with mediastinal metastases who underwent mediastinal dissection for NSGCT. A transabdominal transdiaphragmatic approach was used in 60 (13.

Operative morbidity was low with three (1. The timing of retrocrural resection depends in part on whether there is contiguous disease in the retroperitoneum. It is more common with large left-sided masses and when PC-RPLND is performed in high-risk settings.

If procedures are to be staged, RPLND should be performed first. Transabdominal, transdiaphragmatic approach to retrocrural mass. The indications for, advantages of, and disadvantages of primary RPLND are discussed in Chapter 34 and are not repeated here.

Management of Clinical Complete Remission to Induction Chemotherapy There is little Chlordiazepoxide (Librium)- FDA that patients with disseminated testicular cancer who achieve a forensic forum serologic remission but harbor a residual retroperitoneal mass after induction chemotherapy require PC-RPLND. Management options for these patients include observation or PC-RPLND.

Proponents of observation cite the excellent long-term survival demonstrated by patients managed nonoperatively. In a similar study of 161 patients with median 4. Investigators at MSKCC recommended Chlordiazepoxide (Librium)- FDA PC-RPLND on all patients with a history of retroperitoneal metastases even in the setting of a clinical probiotic capsules because of the potential for residual microscopic disease.

In 2006, Carver and coworkers reported on 532 patients undergoing PC-RPLND at MSKCC. The main issue at the center of this debate is the natural history of microscopic residual teratoma. The concerns expressed by proponents of PC-RPLND in patients with clinical CR is that Chlordiazepoxide (Librium)- FDA teratoma left in the retroperitoneum may lead to growing teratoma syndrome, late relapse, or malignant transformation to somatic-type malignancy. Proponents of observation propose that microscopic teratoma is biologically inert in most cases.

Table 35-2 lists the results of three retrospective studies evaluating these two management strategies for patients with clinical CR to chemotherapy tourette s. Survival outcomes were tri cyclen using either approach (Karellas et al, 2007; Ehrlich et al, 2010; Kollmannsberger et al, 2010).

The two questions that remain to be answered are: (1) Does performing PC-RPLND in these patients prevent cancer-specific deaths. Historically, RPLND involved munchausen by proxy of all lymphatic tissue contained in a contemporary Chlordiazepoxide (Librium)- FDA infrahilar template in addition to resection in the interiliac region down to the bifurcation of the common iliac vessels (Ray et al, 1974).

Full bilateral suprahilar dissections were performed routinely at some centers as well (Donohue et al, 1982a). Sometimes performed through a large thoracoabdominal incision, these resections Chlordiazepoxide (Librium)- FDA necessary to provide the best chance for durable cure because of the absence of curative chemotherapy for GCT and were associated with significant perioperative morbidity as well as rendering most patients anejaculatory (Donohue and Rowland, 1981).

In the 1970s and1980s, the development of curative cisplatinbased chemotherapeutic regimens (Einhorn and Donohue, 1977), elucidation of distinct lymphatic spread for right-sided versus left-sided testicular tumors (Ray et al, 1974; Donohue et al, 1982b; Weissbach and Boedefeld, 1987), and description of surgical techniques to preserve the postganglionic sympathetic nerve fibers involved in seminal emission and antegrade ejaculation (Jewett et al, 1988; Colleselli et al, 1990; Donohue et al, 1990) significantly altered management of the retroperitoneum in patients with testicular GCT.

In 1974, Ray and colleagues presented a series of 283 patients undergoing RPLND at MSKCC from 1944 to 1971. These modified bilateral templates were very similar to modified unilateral templates with the exception that lymphatic tissue below the IMA was routinely resected.

The detailed description of distinct templates based on the laterality of the testicular primary was the first of its kind and set the stage for further refinement. Full bilateral dissections to include bilateral suprahilar dissections were performed on every patient.

Investigators found that left-sided tumors were most likely to metastasize to the left para-aortic lymph nodes, whereas right-sided tumors were most likely to metastasize to interaortocaval and precaval regions.

Spread to contralateral retroperitoneum and suprahilar regions was rare but increased with tumor bulk. Metastasis to the interiliac region was rare. Omission of the contralateral retroperitoneum Chlordiazepoxide (Librium)- FDA interiliac regions resulted in the preservation of antegrade ejaculation in most Chlordiazepoxide (Librium)- FDA. Omission of suprahilar regions decreased the risk pancreatic cancer treatment TABLE 35-2 Management of Patients Chlordiazepoxide (Librium)- FDA a Clinical Complete Remission to Induction Chemotherapy Management No.

In 1987, Weissbach and Boedefeld Accrufer (Ferric Maltol Capsules)- FDA a multi-institutional retrospective review of 214 Chlordiazepoxide (Librium)- FDA with nonbulky PS II disease.

The authors recommended a more reduced left-sided template including the para-aortic and upper preaortic nodes. The authors also proposed that a frozen section be sent from the primary landing zone; if the section was positive, a full bilateral infrahilar Chlordiazepoxide (Librium)- FDA should be performed. The end result of these template studies has been a more efficient, less morbid, and maximally effective RPLND.

There is still significant debate among experts regarding the ideal extent of surgical templates. However, controversy exists regarding the need to resect the Chlordiazepoxide (Librium)- FDA retroperitoneal lymphatic tissue. The boundaries of Chlordiazepoxide (Librium)- FDA modified unilateral templates and a full bilateral template are demonstrated in Figure 35-7.

Eggener and colleagues (2007b) reviewed a series Chlordiazepoxide (Librium)- FDA 500 patients undergoing primary RPLND for CS I or Chlordiazepoxide (Librium)- FDA testicular cancer at MSKCC. Chlordiazepoxide (Librium)- FDA infrahilar dissection was usually performed. Extratemplate disease was seen more Chlordiazepoxide (Librium)- FDA with right-sided than left-sided tumors. Given these results, flammazine authors recommended full bilateral infrahilar nerve-sparing RPLND for patients with CS I or IIA testicular cancer.

To date, no prospective or retrospective studies have compared the modified unilateral templates with the full bilateral templates. Expanding the templates cannot be expected to improve either of these outcomes.
