Breast Conservation Therapy in Patients with Early-Stage Breast Cancer Who Have Undergone a Second Re-Excision of the Primary Tumor Bed: A Report of Four Cases

Abstract: For the women with early-stage breast cancer who are candidates for breast conservation therapy, re-excision of the primary tumor bed has commonly been used in patients for several indications. These indications include positive margin or uncertain margin status of the primary excision or residual microcalcifications on postbiopsy mammogram. If the pathology from the re-excision does not confirm negative margin status, mastectomy is generally recommended. This article examines patients who have undergone a second re-excision (i.e., a lumpectomy followed by two re-excisions) who have been treated with breast conservation therapy rather than a mastectomy.
From September 1977 to November 1995, 1,562 patients underwent breast conserving therapy at this institution. Seven hundred forty of these patients underwent a re-excisional biopsy because of positive or uncertain margin status or residual microcalcifications after the first excision. Four patients (0.5%) underwent a second re-excision because of positive or uncertain margin status or residual microcalcifications on mammogram after the first re-excision. The final margin status after the second re-excision of all four patients was negative. The radiation dose was 4,600–5,000 cGy to the whole breast followed by a conedown to bring the total dose to 6,400–6,800 cGy to the primary tumor bed.
Follow-up in the four patients was 13 years, 4 years, 14 months, and 8 months respectively. All four patients are clinically without disease and have not had a locoregional recurrence. Cosmesis was excellent in all four patients. One patient had an adriamycin-induced recall reaction causing a cellulitis, which resolved with antibiotics. There were no other complications.
Highly selected patients may undergo breast-conserving therapy after a second re-excision. Good outcome and cosmesis can be achieved for this small subset of patients with avoidance of a mastectomy.     

Clinical aspects of blue nevus and its variants

In a 5-years' study, we investigated the correlation between clinical and histological diagnoses of blue nevi. In 24.7% of the cases, the clinical diagnosis turned out to be false; blue nevus was mostly confused with nevomelanocytic nevus (11.2%). Malignant melanoma was the primary differential diagnosis in 13 out of 89 cases. Differentiation of the histological subtypes identified 76.4% of the tumors as common blue nevi and 15.7% as cellular blue nevi. The remaining 7.9% were combined nevi. The average age of the patients with blue nevi at the time of excision was lower than that of the patients suffering from malignant melanoma during the same observation period. Comparison of the distribution of 89 blue nevi with 196 malignant melanomas revealed the different preferred areas of these tumors. We briefly refer to related dermal melanocytoses, such as Mongolian spot and Ota's nevus.     

Coaching. Developing key players.

Coaching provides nurse administrators with a framework for developing their management team. Middle managers who have been coached can use coaching to provide performance feedback and encourage teamwork within their staff. Coaching as a management strategy should be valued and practiced from the nurse executive on down through the organization.     

Der modifizierte erweiterte distal gestielte sapheno-fasziokutane Suralislappen

Zusammenfassung Nach Verifikation der anatomischen Voraussetzungen wurde eine modifizierte Technik des erweiterten saphenofasziokutanen Suralislappen für große kombinierte Knochen-Weichteil-Infekt-Defekt-Situationen sogenannte Typ-C-Läsionen bei Risikopatienten mit ersatzschwachem bzw. ersatzunfähigem Lager (traumatische ipsilaterale arterielle Hauptgefäßläsion, tiefe ipsilaterale Venenthrombose, diabetische Polyneuropathie mit Mikroangiopathie bzw. PAVK Stadium 3) in einer prospektiven Studie angewendet. Zehn Weichteildefekte zwischen 80–180 cm² im Mittel-Rückfuß- bzw. distalen Unterschenkelbereich wurden einzeitig komplett mit einem retrograd gestielten modifizierten saphenofasziokutanen Suralislappen aus dem proximalen Unterschenkel gedeckt. Alle Lappen heilten ohne Lappennekrosen ein. Die Entnahmestellen wurden siebenmal mittels primärer Naht und dreimal einzeitig mit Meshgraft verschlossen. Bei der Nachuntersuchung aller Patienten nach im Mittel 22 Monaten bestanden vitale Lappen, keine Hebedefektmorbidität, kein Suralisneurom und es war kein sekundäres Debulking oder andere lappeninduzierte Revisionen erforderlich.     

The prognostic significance of serum alpha 1-fetoprotein in children and adolescents with malignant extracranial non-testicular germ cell tumors]

The cooperative therapy study MAKEI 83/86 included an examination of the prognostic value of the AFP in children and adolescents with extracranial non-testicular yolk sac tumors. The serum AFP values of 72 protocol- and follow-up-patients were documented at diagnosis and up to the ninth month of treatment. 32 of these patients had saccrococcygeal tumors, 27 had tumors of the ovary and 13 suffered from extragonadal germ cell-tumors. 4 children showed progressive disease under initial chemotherapy and 1 patient died of therapy, 10 of 72 patients relapsed. The AFP measurements were plotted on semilogarithmic charts. They were compared to the measurements of healthy children up to the age of 1 year. According to the development of the patients' AFP values compared to the reference curves the following classifications could be made: 1. Patients with a normal AFP-decrease id est 50% in less than or equal to 6 days during the 1st month of therapy: 48/72 patients 2. Patients with slow AFP-decrease: 17/72 patients 3. Patients with transient AFP-decrease: 5/72 patients 4. Patients with no AFP-decrease: 2/72 patients According to Kaplan-Meier life table analysis, patients with a normal AFP-decrease had an event-free survival of 89% +/- 4%, whereas all other patients showed an event-free survival of 63% +/- 10% (p less than 0.05). Regarding primary therapy id est tumor resection or preoperative chemotherapy an equal distribution of the patients among those with a normal and slow AFP-decrease was observed.(ABSTRACT TRUNCATED AT 250 WORDS)     

Elimination of bacteria on different implant surfaces through photosensitization and soft laser. An in vitro study.

Microbiologic examinations of implants have shown that certain micro‐organisms described as periodontal pathogens may have an influence on the development and the progression of peri‐implant disease. This experimental study aimed to examine the bactericidal effect of irradiation with a soft laser on bacteria associated with peri‐implantitis following exposure to a photo‐sensitizing substance. Platelets made of commercially pure titanium, either with a machined surface or with a hydroxyapatite or plasma‐flame‐sprayed surface or with a corundum‐blasted and etched surface, were incubated with a pure suspension of Actinobacillus actinomyetemcomitans or Porphyromonas gingivalis or Prevotella intermedia. The surfaces were then treated with a toluidine blue solution and irradiated with a diode soft laser with a wave length of 905 nm for 1 min. None of the smears obtained from the thus treated surfaces showed bacterial growth, whereas the smears obtained from surfaces that had been subjected to only one type of treatment showed unchanged growth of every target organism tested ( P <0.0006). Electron microscopic inspection of the thus treated platelets revealed that combined dye/laser treatment resulted in the destruction of bacterial cells. The present in vitro results indicate that lethal photosensitization may be of use for treatment of peri‐implantitis.     

Acute megakaryocytic leukemia in children. Clinical, immunologic, and cytogenetic findings in two patients.

An unusual presentation of acute megakaryocytic leukemia (AMKL) is reported in two young children. The first child had a 10-day history of ptosis of the right eyelid as the initial manifestation of AMKL, a clinical picture not previously described in this variant of leukemia. Computed tomographic scanning showed multiple intracranial mass lesions, and the diagnosis of AMKL was confirmed by immunophenotyping of bone marrow blasts. The second child had Down syndrome and received alkylating agents and radiation therapy for treatment of metastatic rhabdomyosarcoma of the orbit. She had AMKL as second malignancy. Both patients had acquired chromosome 21 anomalies in their leukemic blasts. The first patient, constitutionally normal, had an i(21q) in his leukemic blasts; the patient with constitutional trisomy 21 had tetrasomy 21 and additional chromosomal changes. The clinical symptoms and the results of morphologic, immunologic, and cytogenetic studies are discussed.
