Table 2. Summary of initial treatment, lymphoscintigraphy, and second surgery.
Patient No. | Initial surgery | RT after the initial surgery | 15 min after radioisotope injection | 3 h after radioisotope injection | Surgery | Pathological results of SNB (Number of a metastasis in sentinel lymph nodes/number of lymph nodes extracted) |
---|---|---|---|---|---|---|
1 | Bp+SNB | Done | Not detected | Ipsilateral internal mammary, ipsilateral intramammary and contralateral internal mammary > Ipsilateral axilla | Bt | Not done |
2 | SNB | Not done | Not detected | Not detected | Bt | Not done |
3 | Bp | Done | Ipsilateral axilla | Ipsilateral axilla | Bt+SNB | No metastasis (0/3) |
4 | Bp+SNB | Not done | Not detected | Ipsilateral axilla | Bp+SNB | No metastasis (0/2) |
5 | Bp+SNB | Done | Not detected | Ipsilateral axilla | Bt+SNB | No metastasis (0/3) |
6 | Bp+SNB | Done | Not detected | Ipsilateral internal mammary > contralateral axilla | Bt | Not done |
7 | Bp+SNB | Done | Ipsilateral internal mammary | Ipsilateral internal mammary > Ipsilateral axilla | Bt+SNB | No metastasis (0/1) |
8 | Bp+SNB | Done | Not detected | Ipsilateral internal mammary, subclavicular, contralateral axilla | Ax | Not done |
9 | Bp+SNB | Done | Not detected | Ipsilateral axilla, Ipsilateral internal mammary, contralateral axilla | Bt+SNB | No metastasis (0/1) |
Bt – mastectomy; Bp – partial mastectomy; SNB – sentinel node biopsy; Ax – axillary dissection; RT – radiation therapy. |
