ABSTRACT We examined tumor-related pathologic factors and cone-related characteristics to identify parameters related to recurrence in microinvasive squamous cell carcinoma of the cervix treated with conization. This is a retrospective study on 67 consecutive cases of microinvasive carcinoma of the cervix [depth of invasion (DI) < 3 mm] treated with conization. The mean follow-up was 121 months (range 72-276 months). Four (6%) invasive recurrences were observed. Presence of lymphvascular space involvement (LVSI) was significantly related with recurrences (P < 0.05). The mean distance between tumor margin and apex of the cone (apical clearance) was 10.6 mm (range 5-22 mm), and the mean distance between lateral border of the cone and tumor margin (lateral clearance) was 6.5 mm (range 1.7-15 mm). We adopted cut-off values of 10 and 8 mm for apical and lateral clearances, respectively. We found a statistically significant difference between apical clearance and recurrence rate (P < 0.02). The LVSI was, other than DI, an important prognostic factor. Apical clearance was significantly correlated with recurrence. The cone-related characteristics, other than tumor-related pathologic factors, could help the decision concerning the definitive therapy for microinvasive carcinoma of the cervix.

    ABSTRACT: The α-γ linkage is thought to be critical in the jaw-closing movement due to the structural specificities of the peripheral and central axon terminals of primary sensory neurons in the mesencephalic trigeminal nucleus (MTN). The peripheral axon may supply the large number of annulospiral endings surrounding intrafusal fibers encapsulated in single muscle spindles while the central axon sends only a few number of synapses onto single α-motoneurons (α-MNs). Spike activity in a γ-motoneuron (γ-MN) would induce a large number of impulses in single peripheral axons by activating many intrafusal fibers simultaneously. This would subsequently cause an activation of α-motoneurons (α-MNs) in spite of the small number of synapses. Thus, the activity of γ-MNs may be vital for modulation of jaw-closing movements. Independently of such a spindle activity modulated by γ-MNs, somatic depolarization in MTN neurons is known to trigger the oscillatory activity. Nevertheless, the trafficking of these spikes arising from the two distinct sources of MTN neurons is not well understood. In this short review, multiple functional modes of MTN neurons are discussed. Subsequently, it will be discussed which mode can support the α-γ linkage. In our most recent study, simultaneous patch-clamp recordings from the soma and axon hillock revealed a spike-backpropagation from the spike-initiation site in the stem axon to the soma in response to a somatic current pulse. It was demonstrated in this study that at hyperpolarized membrane potentials, 4-AP-sensitive K+ current exerts two opposing effects on spikes depending on their origins; suppression of spike initiation and facilitation of axonal-spike-invasion at higher frequencies. Through this mechanism, the spindle activity modulated by γ-MNs would be safely forwarded to α-MNs.

    ABSTRACT: Globally, cervical cancer is the second most common malignancy after breast cancer to affect women. Nearly three fourths of all cases occur in developing countries. During the last twenty years the introduction and application of screening programs has been credited with reducing (nearly by one third) the incidence of cervical cancer in the United States. An association between cervical cancer and sexually transmitted human papillomavirus infection has been established years past. HPV/DNA is implicated in the pathogenesis of more than 90% of pre- invasive and invasive cervical lesions. Twenty-one (21%) of all cervical cancer cases are diagnosed in sexually active young women who desire to preserve their fertility. This article reviews current management strategies for microinvasive cervical cancer and considers the mechanisms of therapeutic action.
