Nowadays surgery is still the mainstay of solid tumors treatment. En Bloc resection is surgical treatment in amount of complete tumor removal. There remains considerable uncertainty about many aspects of resection boundaries, including definition and influence of anatomical and histological factors. One of the biggest challenges for the surgeon is choosing the right surgery for the «right» patient, taking into account the type of tumor and its biology.

Anterior Posterior

✓ In cases of primary malignant extradural tumors of the spine, the main goal of the surgery is en bloc resection and reconstruction of the spine. After placing the patient in the lateral position, an en bloc resection of a chondrosarcoma that arose from the right seventh rib head and invaded the adjacent vertebra was performed using a simultaneous anterior—posterior approach followed by spinal reconstruction. The technical details are reported. Paraspinal malignant tumors of the thoracic spine can be safely removed en bloc and the spine reconstructed using this approach.

The Right

A 68-year-old female was operated for a giant dedifferentiated retroperitoneal liposarcoma (RLS) encasing entirely the right kidney. She had an en-bloc resection of the tumor with right nephrectomy. The en-bloc resection should avoid R1 resection margins. Renal conservation is suggested if the kidney is widely displaced and for elderly patient.

Mastoid Bone

Parosteal osteogenic sarcoma (POS) is an uncommon surface bone tumor, most often arising from the metaphyseal end of long bones. Involvement of the cranial bones is rare, with only 1 case of mastoid bone POS previously reported in the literature. Two patients with POS of the mastoid are presented, 1 followed up for 25 years after surgical treatment. The presenting signs and symptoms, as well as distinctive radiographic findings, are discussed. Histologic features are also described. Typically, cranial POS appears as a sessile, densely ossified surface growth with radiating bone spicules that blend with surrounding soft tissue. Treatment is en bloc resection, which is curative in most cases.

Duodenal Invasion

Direct invasion of colorectal adenocarcinoma into adjacent structures occurs frequently, but only rarely is the duodenum involved. This study was undertaken to assess the safety and efficacy of en bloc resection of locally advanced right colon carcinoma invading the duodenum. A retrospective review of 49 patients with locally advanced colon cancer, surgically managed between 2000 and 2005, was performed. Forty-six patients underwent en bloc resection of colon and adjacent organs not involving the duodenum. Three patients with duodenal invasion underwent en bloc partial duodenectomy. The mean operative blood loss, length of stay, postoperative morbidity, and mortality compare favorably between these two groups of patients. Of the 46 patients with en bloc resection of other organs, 27 are alive at 12 to 60 months follow up. Two patients with duodenal invasion are alive without recurrence at 15 and 20 months follow up. En bloc resection of colon cancer invading the duodenum can be performed safely because morbidity and mortality rates are comparable to those attending extended resections of other locally advanced colon carcinomas. Overall survival in patients who underwent surgery with curative intent justifies en bloc duodenal resection in selected patients.

Maxilla And Mandible

Ameloblastomas arising in the supraperiosteal soft tissues (peripheral ameloblastoma) and those taking origin in the maxilla have distinctively different biologic behaviors. The peripheral ameloblastoma can be successfully treated by conservative excision while en bloc resection is warranted for the maxillary ameloblastoma. The effectiveness of primary surgical treatment of an ameloblastoma of the maxilla is the key to reduce morbidity and mortality from the lesion. Anatomic differences between the maxilla and mandible and an apparent more aggressive behavior of maxillary tumors also play a role in establishing the ameloblastoma of the maxilla as the most dangerous of the ameloblastomas.

Skull Base Defects

The treatment of malignant skull base tumors has improved with the development of skull base surgical approaches that allow en bloc resection of a lesion and increase the efficacy of adjuvant therapies. The anatomical complexity of these lesions and their surroundings has led to a relatively high complication rate. Infection and cerebrospinal fluid fistulas are the most common serious procedure-related complications. They result from the frequent necessity of working in a contaminated space such as the paranasal sinuses as well as from the creation of large dural and skull base defects. The authors have reviewed the literature regarding complications of surgery for malignant skull base lesions and present several techniques and strategies for minimizing their incidence by performing the craniofacial approach to anterior skull base lesions.
